For my project, I did P.4 example 8. For the example, you need to find the slope, y2-y1/x2-x1 of the points that were given. After you find the slope, you then plug the slope into the point-slope intercept form, y-y1=m(x-x1) to make a linear equation, Ax+By=C. Then simplify the equation to a point intercept form, y=mx+b where y is by itself. And also graphing the answers I got with the equation..
