Grind 15 - The Line 1
Our first grind on The Line. The Distance, Midpoint and Slope formula from tables p18. It's important to have a good understanding of The Length of a Line Segment and the Midpoint of a Line segment. The slope, of course, is the most important part of this grind.
Try the homework attached and we'll correct in grinds next week.
