Question

A line passes through the points (8, 7) and (5, 1). What is its equation in slope-intercept form?

Answer 1

y = 2x - 9

Explanation:

Y2 - Y1/X2 - X1

7 - 1/8 - 5

6/3

= 2

y = 2x + b

1 = 2(5) + b

1 = 10 + b

-9 = b

y = 2x - 9

Answer 2

y=2x-9

Explanation:

The slope is 2 and the y-intercept is -9
