## Algebra and Trigonometry 10th Edition

$m=\frac{y_2-y_1}{x_2-x_1}$ (Pick 2 points on the line and use them to find the slope of the line) $m=\frac{-150-(-50)}{1800-600}=-100/1200=-1/12$ y=mx+b (Use the slope and one of the chosen points to find the equation of the line) -150=-(1800)/12+b -150=-150+b b=0 y=-x/12
