Question

1. The sliders for y = ax + b have been set to create the following graph. What are possible values for a and b?

Answer 1

The slope of the line is m = 2 and the y-intercept b = 2

Therefore, the equation for the graph is

`y=-2|x|+2`

meaning a = -2 and b = 2.

(The negative sign in front of the absolute value drags the graph below the y = 0 )
