Question

Write the point-slope form of the equation of the line with a slope of - 2 and an x-intercept of - 1. Include your work in your final answer.

Please helps and show how.

Answer 1

y= -2x-2

Explanation:

point slope- y=mx+b

y-y1=m(x-x1)

you have the point (-1,0) and you have to use (x1, y1)

your slope is -2

Substitute

y-0= -2(x +1)

Distribute

y-0=-2x-2

+0 +0

y= -2x-2

Answer 2

well, if the x-intercept is at x = -1, what's y? well, is an x-intercept, y = 0, so the point is -1, 0.
