Question

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

Answer 1

Answer:

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

$y=-4x+8$

Step-by-step 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)

$y=-4x+8$
