 In this video we provide the solution to question number one from the practice exam number two for math 10 50 Which case we're given two points one one and three two and we're asked to find the slope of the line passing through these points So we'll want to use our slope formula m equals y 2 minus y 1 over x 2 minus x 1 It doesn't matter which point is considered the first one which ones the second one as long as you're consistent So let's take 2 minus 1 so the difference of the y coordinates the rise Divided by 3 minus 1 the difference of the x coordinates or the run So we end up with 1 over 2 and so we see the correct answer would be choice B
