we have that
1) Relationship B has a lesser rate than Relationship A
2) The graph represents Relationship A
we know that
The rate is equal to the slope of the linear equation in the graph
Step 1
<u>Find the slope of the Relationship A</u>
we have

we know that
The formula to find the slope m between two points is equal to

substitute the values



Step 2
<u>Find the equation that could represent Relationship B</u>
we know that
Relationship B has a lesser rate than Relationship A
so
the slope of the Relationship B is less to the slope of the Relationship A

therefore
<u>the answer is</u>
------> because the slope is 
------> because the slope is
