Answer:
36
Step-by-step explanation:
Slope (m) = change in Y over change in X
change in Y = 9-5 = 4
change in x = 8-4 = 4
slope = 4/4 = 1
m = 1
the y intercept (b) would be found by using the formula y = mx+b
find b by replacing y, m and x in the equation with one of the points and the calculated slope:
(4,5) x = 4, y = 5 and slope m = 1
5 = 1*4 +b
5 = 4+b
b = 5-4
b=1
so the equation of the line would be y = x +1
the answer is A
