4. (12 pts} Consider the points (2, -7) and (-2, l). (a) Find the slopeintercept equation of the line passing through the two given points. Show work. (1)) Graph the line you found in (a), either drawing it on the grid in the previous problem #3, or generating the graph electronically and attaching it. (c) Compare your line for this problem, #4, with the line in the previous problem #3. Are the two lines parallel, perpendicular, or neither parallel nor perpendicular? (The terms parallel and perpendicular are discussed on pages 166 and 167.) No explanation required just state the
