Step-by-step explanation:
If you notice, we have been given two points on the line graph which are enough for us to get its slope;
The obvious point is (1,8)
The second point where the line intercepts X-axis (at this point y = 0). Therefore;
(-1,0)
Slope = (y2 – y1) / (x2 – x1)
= (8 – 0) / (1-(-1)) = 8/2 = 4
