Question

The values of z and y vary together at a constant rate of change such that Ay = 0.5Ar. (This information applies to
all three parts.)
%3D
a, Suppose the value of r varies from z 1.5 to z -3. Your classmate comes to you after calculating the
change in a for this interval:
Ar = 0.5(-3 - 1.5) = -2.25
Are they right? (Select the one best choice.)
ONo. They calculated Ay instead.
ONo. They used addition instead of subtraction.
ONo. They subtracted in the wrong order.
O Yes. This is the change in z.
b. Suppose the change in e between two points in this relationship is 5. Another classmate has calculated the
corresponding change in y:
Ay = 5
Are they right? (Select the one best choice.)
ONo. This is the change in z.
ONo. The change in y should be the same sign as the change in x.
O No. They divided instead of multiplied.
O Yes. This is the change in y.
