Question

Susie determined that the system of equations below has infinitely many solutions.

The first line goes through the points (2, -13) and (-2, -1).

The second line goes through the points (5, -22) and (-3, 2).

Is she correct?

Answer 1

I don't think she is correct because the of the points (2, -13) and (5,-22) are not the same line...

Answer 2

Put the steps in order that are used to solve the following systems of equations by substitution.

−7x−2y=−13

x−2y=11
