Answer:
y intercept = - 40
Step-by-step explanation:
x 24 36 48
y -8 1 10
y = ax + b
a is the gradient (or slope).
b = y intercept.
a = (48-36) / (10-1) = 12/9
Rewrite to solve for b, which means it starts with b = ...
b = y - 12/9 * x
Substitute one point ( 24 , -8 )
b = -8 - (12/9 * 24)
b = y intercept = - 40
I believe A. would be the answer
SORRY IF WRONG
