The slope is 1. Find ordered pairs ( 1 , -4 ) ( 3, 3) The formula is M= y2 - y1 _____ X2- X1 2. Replace the numbers M = 3 - 4. ——— 1-3 Subtract 3. You get -1/-2 4. Divide you get 0.5 ( but if you need rise and run use -1/-2) rise top run bottom Slope is 0.5 I think Hope this helps here a picture of my lesson.
