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.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.
