Answer 6

Constant relationship

Question 7

What is the relationship of a peak graph?

Answer 7

A peak in a graph represents where the data was the best, or highest, in relation to results and correlation.

Question 8

What is the relation of a non-linear graph?

Answer 8

As one variable increases, the other increases by inconsistent amounts.

Question 9

What is the difference of interpolation and extrapolations?

Answer 9

Interpolation - to make predictions within recorded data
Extrapolation - to make predictions about data not yet recorded

Question 10

Answer 10

Direct

Question 11

True or False:
The variable measured is the dependent variable, and it is found on the x-axis

false; although the dependent variable is being measured, it is found on the y-axis

Question 12

While drawing a graph, you should not connect the dots

Answer 12

true; unless instructed otherwise, you should find the line of best fit

Question 13

True or False:
You should only use 1/4 of the graph space provided
