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. Type your answer in the box provided or use the upload option to submit your solution.

Answer 1

y-b=m(x-a) where (a,b) is a point and m is the slope


y - 0 = -2(x+1)

Answer 2

Slope-intercept form: y = -2x - 1. Convert this to point-slope form:

Find a point on the graph. It's (0, -1), since y = -2(0) - 1 = -1.

Then the point-slope form is

y-(-1) = -2(x - 0)
