Answer:

y = -9x +49

Explanation:

The slope of line b is the same as the slope of line a. That can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (-1 -8)/(2 -1) = -9

The y-intercept can be found from the given point using the formula ...

b = y - mx

b = 13 -(-9)(4) = 13 +36 = 49

Then the slope-intercept equation of line b is ...

y = -9x +49
