Algebra 1: Common Core (15th Edition)

You have to put it into slope-intercept form. Use two points (-3,-6)(2,4) and use the slope formula (m=$\frac{y2-y1}{x2-x1}$): m=$\frac{4-(-6)}{2-(-3)}$=$\frac{10}{5}$=2. The slope is 2. Plug the slope and the two points into y-y1=m(m-x1): y-4=2(x-2) Put it into slope intercept formula too: y=mx+b 4=2(2)+b 4=4+b 0=b b-0 The slope is 2 and the y-intercept is 0 so the equation is y=2x.
