You've been given two points, (x, f(x)) = (2, 3) and (x, f(x)) = (6, -3). Plug these points into slope formula. Then pick one of the points (it doesn't matter which one), and plug that point and the slope you just found into one of the forms of the equation of a straight line.
If you get stuck, please reply showing how far you have gotten in working through these steps. Thank you!
