The point of intersection for two linear functions.

1. Get the two equations for the lines into slope-intercept form. That is, have them in this form: y = mx + b.
2. Set the two equations for y equal to each other.
3. Solve for x. This will be the x-coordinate for the point of intersection.
4. Use this x-coordinate and plug it into either of the original equations for the lines and solve for y. This will be the y-coordinate of the point of intersection.
5. As a check for your work plug the x-coordinate into the other equation and you should get the same y-coordinate.
6. You now have the x-coordinate and y-coordinate for the point of intersection.
