4-91.

Kenneth claims that (2, 0) is the point of intersection of the lines y = −2x + 4 and y = x − 2. Is he correct? How do you know? Homework Help ✎

Check his work by substituting (2, 0) into each equation.

y = −2x + 4
0 = −2(2) + 4

True or false?

Check the other equation.

(2, 0) is a solution to both equations, so it is where the two lines intersect.
