Rearrange the equation so you have y = 2x

Then, plug in numbers to this equation.

Rearrange the equation so you have y = 2x

Then, plug in numbers to this equation.

When x = -2 y = 2x-2 = -4

When x = -1 y = 2x-1 = -2

When x = 0 y = 2x0 = 0

When x =1 y = 2x1 = 2

When x = 2 y = 2x2 = 4

This is what the graph would look like:

graph{2x [-7.686, 6.43, -2.413, 4.937]}
