Question

Write the equation of the line in fully simplified slope-intercept form.

Answer 1

y = -x - 8

Explanation:

(-8,0) and (-9,1) are 2 points on the line. You can pick any 2 points.

slope = rise/run = (y2-y1)/(x2-x1) = (0-1)/(-8 - -9) = -1/1 = -1

The y intercept is -8.

The slope intercept formula y = mx + b where m is the slope and b is the y intercept.

So the equation is y = -x - 8

Answer 2

Explanation:

(-9, 1), (0, -8)

(-8 - 1)/(0 + 9) = -9/9 = -1

y - 1 = -1(x + 9)

y - 1 = -x - 9

y = -x - 8
