To make a table of values, you have to know the equation. You are only given a point, and a gradient. This means you must derive the equation. If the gradient is 2, then we can use the equation to write:

You know that the point (-4,-2) is on the line. This means that:

Sovling for b:

The equation of the line can now be written.

To find the point where the lines intersect, you have to solve the system of equations:

y=2x+6

y=-x+2

The solutions for x and y will give the point of intersection.
