Answer:
y=-1/4x-6
Step-by-step explanation:
The equation of a line is:
y=mx+b (slope-intercept form) where m is the slope and b is the y-intercept. x and y are the x and y coordinates for a point on the line.
Now that we know the equation, we plug in the given numbers into the equation:
y=mx+b
-8=-1/4(8)+b
-8=-2+b
b=-6
Now we know the y-intercept so the equation is:
y=-1/4x-6
