We are given the equations:
y = 5.05x
y = 0.55x
y = 5.5x
And the points (11, -2), (-20, -11), (2, 11)
It's required to match equations with their solutions.
The first point can be discarded because its input is positive and the output is negative. None of the equations has a negative coefficient, so it cannot be a solution of any of them.
Testing the point (-20, -11) in the three equations:
y = 5.05*(-20) = -101
y = 0.55*(-20) = -11
y = 5.5*(-20) = -110
This point corresponds to the second equation.
Testing the point (2, 11) on the remaining equiations:
y = 5.05*(2) = -11.1
y = 5.5*(2) = 11
This point corresponds to the last equation.
