It is relatively easy to determine whether an equation is a function by solving for y.
When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value, than you have a function.
the equation y=-7x%2B12 is a function
you can also prove it using vertical and horizontal line test
