Question

Relationship B has a greater rate than Relationship A. The graph represents Relationship A. Which equations could represent Relationship B?

Choose all answers that are correct.

y = 1/2 x

y=2.2x

7=1.4x

y=3x

Answer 1

relationship A has a slope of 2....so relationship B needs to have a higher slope (rate of change).

so relationship B can be : y = 2.2x or y = 3x

Answer 2

The slope of relationship A:
slope = change in y / change in x
m = (8 - 4) / (4 - 2)
m = 2

Thus, the slope of relationship B must be greater than 2.

The answers are:
y = 2.2x
y = 3x
