Question

Given that the equation y=mx + b where m is 12 and the line passes through the point (-2,8), what would be the value of b?

a. b = -16
b. b = -8
c. b = 16
d. b = 32

Answer 1

d

Explanation:

The answer would be D. We can continue the line from the point (-2,8) because we know the slope so we will continue it forward by two on the x axis. Since we go forward by two we are going up by 24 (12*2) on the y axis so the y intercept (b) would be 8 + 24 which is 32. Sorry if it is hard to understand.
