Answer:
The rule for a line whose gradient is -4 and y-intercept = 8 is
[tex]y=-4x+8[/tex]
Step-by-step explanation:
Equation of line slope intercept form is
[tex]y=mx+b[/tex] ------------- (1)
Where m is slope or gradient and b is y-intercept
Here
[tex]m=-4 \ \ \ and \ \ \ b=8[/tex]
Substituting values in equation (1)
[tex]y=-4x+8[/tex]
