Step 1: Solve two equations(linear equations in two variables) to find the coordinate (x or y) at the point of intersection


NOTE: If line intersecting the y-axis then put x = 0 in the equation or

If line intersecting the x-axis then put y = 0 in the equation.


EXAMPLE: y = 2x + 3, y = -0.5x + 7

Setting the two y-coordinates equal looks like this:

2x + 3 = -0.5x + 7

2.5x + 3 = 7

2.5x = 4

x = 4/2.5

x = 1.6

You can follow any method to solve the equations


Step 2: Substitute the coordinator (calculated in step 1) in the either of the equations to find the another coordinate. (x or y)


NOTE: The y-coordinate can be found by placing the x-coordinate, into either of the equations for the lines and solving for y vise versa.


Step 3: You now have the x-coordinate and y-coordinate for the point of intersection.


NOTE: As a check for your work plug the x-coordinate into the other equation and you should get the same y-coordinate.
