Gradient Intercept Form: $y=mx+b$

$m$ is the gradient of the line

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

For: $y=3/4x-3$

The gradient $(m)$ is $3/4$ and the y-intercept $(b)$ is $-3$ .

First, plot the y-intercept $(-3)$

Use the gradient $m=3/4$ to plot the next point.

The gradient is equivalent to the rise over the run.

$(color(darkviolet)(text(rise)))/(color(forestgreen)(text(run)))=(color(darkviolet)(3))/(color(forestgreen)(4))$

From the y-intercept rise $3$ units, then run $4$ units to the right

Now we can graph the equation

Incorrect
Gradient Intercept Form: $y=mx+b$

$m$ is the gradient of the line

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

For: $y=-1/4x+3$

The gradient $(m)$ is $-1/4$ and the y-intercept $(b)$ is $3$ .

First, plot the y-intercept $(3)$

Use the gradient $m=-1/4$ to plot the next point.

The gradient is equivalent to the rise over the run.

$(color(darkviolet)(text(rise)))/(color(forestgreen)(text(run)))=(color(darkviolet)(-1))/(color(forestgreen)(4))$

From the y-intercept rise $-1$ units, then run $4$ units to the right

Now we can graph the equation

Incorrect
Gradient Intercept Form: $y=mx+b$

$m$ is the gradient of the line

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

For: $y=5/3x+1$

The gradient $(m)$ is $5/3$ and the y-intercept $(b)$ is $1$ .

First, plot the y-intercept $(1)$

Use the gradient $m=5/3$ to plot the next point.

The gradient is equivalent to the rise over the run.

$(color(darkviolet)(text(rise)))/(color(forestgreen)(text(run)))=(color(darkviolet)(5))/(color(forestgreen)(3))$

From the y-intercept rise $5$ units, then run $3$ units to the right

Now we can graph the equation

Incorrect
Gradient Intercept Form: $y=mx+b$

$m$ is the gradient of the line

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

For: $y=-5/8x+2$

The gradient $(m)$ is $-5/8$ and the y-intercept $(b)$ is $2$ .

First, plot the y-intercept $(2)$

Use the gradient $m=-5/8$ to plot the next point.

The gradient is equivalent to the rise over the run.

$(color(darkviolet)(text(rise)))/(color(forestgreen)(text(run)))=(color(darkviolet)(-5))/(color(forestgreen)(8))$

From the y-intercept move down $-5$ units, then run $8$ units to the right

Now we can graph the equation

Incorrect
Gradient Intercept Form: $y=mx+b$

$m$ is the gradient of the line

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

For: $y=-3x+3$

The gradient $(m)$ is $-3$ and the y-intercept $(b)$ is $3$ .

First, plot the y-intercept $(3)$

Use the gradient $m=-3$ to plot the next point.

The gradient is equivalent to the rise over the run.

$(color(darkviolet)(text(rise)))/(color(forestgreen)(text(run)))=(color(darkviolet)(-3))/(color(forestgreen)(1))$

From the y-intercept move down $-3$ units, then run $1$ unit to the right

Now we can graph the equation

Incorrect
Gradient Intercept Form: $y=mx+b$

$m$ is the gradient of the line

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

For: $y=2x-5$

The gradient $(m)$ is $2$ and the y-intercept $(b)$ is $-5$ .

First, plot the y-intercept $(-5)$

Use the gradient $m=2$ to plot the next point.

The gradient is equivalent to the rise over the run.

$(color(darkviolet)(text(rise)))/(color(forestgreen)(text(run)))=(color(darkviolet)(2))/(color(forestgreen)(1))$

From the y-intercept rise $2$ units, then run $1$ units to the right

Now we can graph the equation

Incorrect
Gradient Intercept Form: $y=mx+b$

$m$ is the gradient of the line

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

For: $y=4/5x+3$

The gradient $(m)$ is $4/5$ and the y-intercept $(b)$ is $3$ .

First, plot the y-intercept $(3)$

Use the gradient $m=4/5$ to plot the next point.

The gradient is equivalent to the rise over the run.

$(color(darkviolet)(text(rise)))/(color(forestgreen)(text(run)))=(color(darkviolet)(4))/(color(forestgreen)(5))$

From the y-intercept rise $4$ units, then run $5$ units to the right

Now we can graph the equation

For: $y=-3/8x-4$

The gradient $(m)$ is $-3/8$ and the y-intercept $(b)$ is $-4$ .

First, plot the y-intercept $(-4)$

Use the gradient $m=-3/8$ to plot the next point.

The gradient is equivalent to the rise over the run.
