step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

f(x)=4
