## Algebra 1: Common Core (15th Edition)

You have to put it into slope-intercept form. Use two points (2,1)(0,2) and use the slope formula (m=$\frac{y2-y1}{x2-x1}$): m=$\frac{1-(-1)}{2-0}$=$\frac{3}{2}$=1.5 The slope is 1.5. Plug it into the slope-intercept form: y=mx+b 1=1.5(-2)+b b=-2 Put the values into the equation: y=-1.5x-2.
