Question

For 30 points (messed up on the last question)

Answer 1

Answer: 4

Explanation:

The constant of proportionality is the slope of a line that goes through the origin.

The slope/constant of proportionality is how much the Y increases every time the X increases by 1. Since your graph has the point (1, 4) labeled, the Y goes up 4 units for every 1 unit the X increases by.

Answer 2

4

Explanation:

Take any point other than (0,0) that is on the line and put it in the form 7/x and that will give you your constant of proportionality.

For example the point graphed is (1,4) 1 is the x value and 4 is the y value.

4/1 = 4
