Question

x y
2.6 −6
3.2 3
Determine the rate of change of the linear function given as a table of values.

m=15

m=−15

m=0.067

m=−5

Answer 1

The correct answer is m = 15.

The rate of change is determined by finding the difference in y-values divided by the difference in x-values.

For the given table of values, the difference in y-values is (-6-3) = -9 and the difference in x-values is (3.2-2.6) = 0.6.

Therefore, the rate of change is -9/0.6 = -15.
