Match the following: a. when two variables change in the same direction, one remaining larger than the other by the same factor b. to insert between neighboring points or estimate by taking an average of known values c. a relationship between two variables in which the product remains constant. when one variable increases the other decreases in proportion so that the product is unchanged 1. direct relationship2. interpolate 3. inverse relationship

a. When two variables change in the same direction, one remaining larger than the other by the same factor - direct relationship

b. To insert between neighboring points or estimate by taking an average of known values - interpolate

c. A relationship between two variables in which the product remains constant. When one variable increases the other decreases in proportion so that the product is unchanged - inverse relationship

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !
