Answer:
y= 4x +16
Step-by-step explanation:
slope-intercept form:
y=mx+c, where m is the gradient and c is the y-intercept
Given that the slope is 4, m=4.
y= 4x+c
To find the value of c, substitute a coordinate.
When x= -5, y= -4,
-4= 4(-5) +c
-4= -20 +c
c= 20 -4
c=16
Thus, the equation of the line is y= 4x+16.
