## Elementary Geometry for College Students (6th Edition)

The line contains(0,b) and (a,0) To find the equation of the line. To use the point slope form, we need to find the slope of the line using (-2,0) and (4,3) m = $\frac{y2-y1}{x2-x1}$ = $\frac{0-b}{a-0}$ =$\frac{-b}{a}$ then, y-y1 = m(x-x1) y-b =$\frac{-b}{a}$ (x-0) y - b= $\frac{-b}{a}$ x ay - ab = -bx bx+ay = ab
