Problem BB-66 Algebra 2

If you have an equation where y isn't equal to something, like your equation x+y=5, then you would have to solve for y. Then, to find out the intersection of two linear equation or lines, you have to set them equal to each other. By doing this, you will find out the x-coordinate. To find out the y-coordinate, plug in your answer for x and solve for y. When you have the x-coordinate and y-coordinate, then you have the intersection of the two graphs.
