What is the solution to the system of equations represented by (1,3)?

Back

The solution (1,3) indicates that x = 1 and y = 3 satisfy both equations in the system.

How do you find the x and y intercepts of the equation 4x - 5y = 40?

Back

To find the x-intercept, set y = 0: 4x = 40, so x = 10. To find the y-intercept, set x = 0: -5y = 40, so y = -8.
