M and want to find other points on the line. Sometimes you would see it written as y2 minus y1 over x2 minus x1 where you could kind of view x1 y1 as the starting point and x2 y2 as the ending point. Finding the Formula of the Line.
Well use the first one to find a formula.
M 69 80 m 6 - 9 8 - 0 Simplify. Well use the first one to find a formula. We also have a point that is on the line namely -6-8 so we can make use of that point to find b. Make sure this slope makes sense by.
