Answer:

The equation y = -3r + 13 does not belong with the other three.

Explanation:

We have 4 equations

  • y = -5x
  • 2x - y = 8
  • y = x + 4
  • y = -3r + 13

The first 3 equations have relations between two variables x and y

So they are linear equations of two variables x and y

The fourth equation has a relation between two variables r and y

So it is a linear equation of two variables r and y

The fourth equation does not belong to with the first three equations because it has a different variable r

The equation y = -3r + 13 does not belong with the other three.
