does this seem like a good explantion

First thing to do is to find the equation in y=mx+b form ..... so our equation is y=3/1x-3 we found our slop with rise over run we found our "-3" from the y-intercept. now all we have to do is to plug the points (4,-3) into out equation if we get a true statement then its is a solution if not it will be false ...-3=3/1(4)-3 .... solving it i get false
