Given the graph of a line y=−x. write an equation of a line which is perpendicular and goes through the point (8,2).

2x - 20 = 32 20 - 3x = 8 6x - 8 = 16 -13 - 3x = -10

Segment ab is shown on the graph. which shows how to find the x-coordinate of the point that will divide ab into a 2: 3 ratio using the formula
