Question

The rule for a line whose gradient is
-4 and y-intercept = 8 is:

Answer 1

The rule for a line whose gradient is -4 and y-intercept = 8 is

`y=-4x+8`

Explanation:

Equation of line slope intercept form is

`y=mx+b` ------------- (1)

Where m is slope or gradient and b is y-intercept

Here

`m=-4 \ \ \ and \ \ \ b=8`

Substituting values in equation (1)

`y=-4x+8`
