Perpendicular lines have gradients which are negative reciprocals of one another.

Gradient Intercept Form: $y = m x + b$ $y=mx+b$

$m$ $m$ is the gradient of the line

$b$ $b$ is the y-intercept (where the line cuts the y-axis)

The gradient is given by the coefficient of $x$ $x$ or the value of $m$ $m$ .

$y$ $y$ $=$ $=$ $- \frac{1}{2} x + 4$ $-1/2x+4$

$m$ $m$ $=$ $=$ $- \frac{1}{2}$ $-1/2$

$y$ $y$ $=$ $=$ $2 x - 3$ $2x-3$

$m$ $m$ $=$ $=$ $2$ $2$

The gradients are negative reciprocals of each other, so the lines are perpendicular or are at right angles with each other.

The lines are perpendicular.

Question 2 of 5

2. Question

Find the equation of a line that passes through

(4, 2)

$(4,2)$ and is perpendicular to

y = - \frac{1}{2} x + 9

$y=-1/2x+9$

1. $y = 5 x - 1$ $y=5x-1$
2. $y = 2 x - 6$ $y=2x-6$
3. $y = - 2 x + 3$ $y=-2x+3$
4. $3 x + 2 y = 1$ $3x+2y=1$

Point Gradient Form: $y -$ $y-$ $y_{1}$ $y_1$ $=$ $=$ $m$ $m$ $(x -$ $(x-$ $x_{1}$ $x_1$ $)$ $)$

$m$ $m$ is the gradient of the line
$(x_{1}, y_{1})$ $(x_1,y_1)$ is a point that lies on the line

Remember

The gradients of perpendicular lines are negative reciprocals of each other.

First, identify the gradient of the given equation.

In gradient-intercept form

(y =

$(y=$ $m$ $m$

x + b)

$x+b)$ , $m$ $m$ is the gradient.

$y$ $y$	$=$ $=$	$- \frac{1}{2}$ $-1/2$ $x + 9$ $x+9$

$m_{1}$ $m_1$	$=$ $=$	$- \frac{1}{2}$ $-1/2$

Get the negative reciprocal of the

m_{1}

$m_1$ by flipping it upside down and changing the sign.

$m_{1}$ $m_1$	$=$ $=$	$- \frac{1}{2}$ $-1/2$

	$=$ $=$	$- 2$ $-2$	Flip the number upside down
$m_{2}$ $m_2$	$=$ $=$	$2$ $2$	Change the sign

Use the Point Gradient Formula to find the equation.

Point:

(x_{1}, y_{1}) = (4, 2)

$(x_1,y_1)=(4,2)$

Gradient:

m_{2} = 2

$m_2=2$

$y -$ $y-$ $y_{1}$ $y_1$	$=$ $=$	$m$ $m$ $(x -$ $(x-$ $x_{1}$ $x_1$ $)$ $)$	Point Gradient Formula
$y -$ $y-$ $2$ $2$	$=$ $=$	$2$ $2$ $(x -$ $(x-$ $4$ $4$ $)$ $)$	Substitute values
$y - 2$ $y-2$	$=$ $=$	$2 x - 8$ $2x-8$
$y - 2$ $y-2$ $+ 2$ $+2$	$=$ $=$	$2 x - 8$ $2x-8$ $+ 2$ $+2$	Add $2$ $2$ to both sides
$y$ $y$	$=$ $=$	$2 x - 6$ $2x-6$	Simplify

y = 2 x - 6

$y=2x-6$

Question 3 of 5

3. Question

(6, 4)

$(6,4)$ and is perpendicular to

3 x - 4 y + 8 = 0

$3x-4y+8=0$

1. $y = - \frac{4}{3} x - 12$ $y=-4/3x-12$
2. $y = - \frac{4}{3} x + 12$ $y=-4/3x+12$
3. $y = \frac{4}{3} x + 12$ $y=4/3x+12$
4. $y = \frac{3}{4} x + 12$ $y=3/4x+12$

Point Gradient Form: $y -$ $y-$ $y_{1}$ $y_1$ $=$ $=$ $m$ $m$ $(x -$ $(x-$ $x_{1}$ $x_1$ $)$ $)$

$m$ $m$ is the gradient of the line
$(x_{1}, y_{1})$ $(x_1,y_1)$ is a point that lies on the line

Remember

The gradients of perpendicular lines are negative reciprocals of each other.

First, convert the equation into gradient-intercept form and identify the gradient.

In gradient-intercept form

(y =

$(y=$ $m$ $m$

x + b)

$x+b)$ , $m$ $m$ is the gradient.

$3 x - 4 y + 8$ $3x-4y+8$	$=$ $=$	$0$ $0$
$3 x - 4 y + 8$ $3x-4y+8$ $+ 4 y$ $+4y$	$=$ $=$	$0$ $0$ $+ 4 y$ $+4y$	Add $4 y$ $4y$ on both sides
$3 x + 8$ $3x+8$	$=$ $=$	$4 y$ $4y$

$\frac{3}{4} x + \frac{8}{4}$ $3/4x+8/4$	$=$ $=$	$\frac{4}{4} y$ $4/4y$	Divide all terms by $4$ $4$

$\frac{3}{4} x + 2$ $3/4 x + 2$	$=$ $=$	$y$ $y$

$y$ $y$	$=$ $=$	$\frac{3}{4}$ $3/4$ $x + 2$ $x+2$	Identify the slope

$m_{1}$ $m_1$	$=$ $=$	$\frac{3}{4}$ $3/4$

Get the negative reciprocal of the

m_{1}

$m_1$ by flipping it upside down and changing the sign.

$m_{1}$ $m_1$	$=$ $=$	$\frac{3}{4}$ $3/4$

	$=$ $=$	$- \frac{4}{3}$ $-4/3$	Flip the number upside down

$m_{2}$ $m_2$	$=$ $=$	$- \frac{4}{3}$ $-4/3$	Change the sign

Use the Point Gradient Formula to find the equation.

Point:

(x_{1}, y_{1}) = (6, 4)

$(x_1,y_1)=(6,4)$

Gradient:

m_{2} = 2

$m_2=2$

$y -$ $y-$ $y_{1}$ $y_1$	$=$ $=$	$m$ $m$ $(x -$ $(x-$ $x_{1}$ $x_1$ $)$ $)$	Point Gradient Formula

$y -$ $y-$ $4$ $4$	$=$ $=$	$- \frac{4}{3}$ $-4/3$ $(x -$ $(x-$ $6$ $6$ $)$ $)$	Substitute values

$y - 4$ $y-4$	$=$ $=$	$- \frac{4}{3} x + 8$ $-4/3x+8$

$y - 4$ $y-4$ $+ 4$ $+4$	$=$ $=$	$- \frac{4}{3} x + 8$ $-4/3x + 8$ $+ 4$ $+4$	Add $4$ $4$ to both sides

$y$ $y$	$=$ $=$	$- \frac{4}{3} x + 12$ $-4/3x +12$	Simplify

y = - \frac{4}{3} x + 12

$y=-4/3x+12$

Gradient Intercept Form: $y =$ $y=$ $m$ $m$ $x +$ $x+$ $b$ $b$

$m$ $m$ is the gradient of the line
$b$ $b$ is the y-intercept (where the line cuts the y-axis)

Remember

To prove the perpendicularity of two lines, the product of their gradients should be equal to $- 1$ $-1$

First, solve for the gradient of each line using the gradient formula

Line 1

$y$ $y$	$=$ $=$	$2$ $2$ $x + 5$ $x+5$
$m_{1}$ $m_1$	$=$ $=$	$2$ $2$

Line 2

$x + 2 y - 6$ $x+2y-6$	$=$ $=$	$0$ $0$
$x + 2 y - 6$ $x+2y-6$ $- x + 6$ $-x+6$	$=$ $=$	$0$ $0$ $- x + 6$ $-x+6$	Add $- x + 6$ $-x+6$ to both sides
$2 y$ $2y$	$=$ $=$	$- x + 6$ $-x+6$	Simplify
$2 y$ $2y$ $\div 2$ $-:2$	$=$ $=$	$(- x + 6)$ $(-x+6)$ $\div 2$ $-:2$	Divide both sides by $2$ $2$
$y$ $y$	$=$ $=$	$- \frac{1}{2}$ $-1/2$ $x + 3$ $x + 3$

$m_{2}$ $m_2$	$=$ $=$	$- \frac{1}{2}$ $-1/2$

To prove that these two lines are perpendicular, check if the product of the two gradients is equal to

- 1

$-1$ .

$m_{1} \times m_{2}$ $m_1 times m_2$	$=$ $=$	$2 \times - \frac{1}{2}$ $2 times-1/2$
	$=$ $=$	$- 1$ $-1$

Therefore, Line

$1$ and Line

2

$2$ are perpendicular.
