x-y=10 Start with the given equation


Let's test the first solution (5,-5):


%285%29-%28-5%29=10 Plug in x=5 and y=-5


10=10 Simplify. Since the two sides of the equation are equal, this means (5,-5) is a solution to x-y=10

Notice if we graph the equation x-y=10 and plot the points (5,-5), we get:

Here we can see that the point (5,-5) lies on the line. This are the solution to the equation x-y=10.
