Question

The two lines shown intersect at the point (a,b). Find ab. Each unit square in the grid represents a distance of 1.

Answer 1

(9/5, 8/5)

Explanation:

First you want to find the equations of the lines. One line is y = 2x - 2 and the other line is y = 1/3x + 1. Then you want to find the x and y that both work in the two equations.

y = 2x - 2

y = 1/3x + 1

Then you do 2x - 2 = 1/3x + 1

Then you do some maths and you get 9/5, and 8/5
