Question

Write the equation of the line in point-slope form given the line runs through the points (-1, -3) and (2, 3). ***rewrite in slope-intercept form by solving for y!

Answer 1

First, find the slope: m=[(3-(-3)]/[(2-(-1)]=2
point slope form: (y+3)=2(x+1) or (y-3)=2(x-2)

slope-intercept form: y+3=2(x+1) => y+3=2x+2 =>y=2x-1
