I dont understand bc all of the y/x come out different. Plz help

  A.  y = 0.45x +7

Step-by-step explanation:

When the y/x come out different, it means the relation is not a proportion. So, the "rate of change" need to be computed from ∆y/∆x, not y/x.

∆y is the difference between two y-values. If we use the first two columns of the table, we have ...

  ∆y = 6.2 -5.4 = 0.8

  ∆x = 3 - 1 = 2

Then the rate of change shown in the table is ∆y/∆x = 0.8/2 = 0.4.

__

For the equations, the rate of change is the coefficient of x. Those are ...

  0.45, -1/2, 0.2, 1/10

If we were to put these rates of change in order on a number line, that order would be ...

  -1/2 < 1/10 < 0.2 < 0.4 < 0.45

A: y = 0.45x+7 has a greater rate of change than shown in the table.
