Answer:
A. -4
Step-by-step explanation:
Slope is rise over run, or y2-y1 / x2-x1.

<u>The slope is A. -4.</u>
Let's see--does that make sense? A slope of four would be pretty steep, and that matches the graph. It also should be negative because the line goes down and to the right, not up and to the right, so -4 makes sense!
I don't know what to do but I think it is #1
Answer:
0.5
Step-by-step explanation:
We are looking for how much height is gained per cup added.
Height per cup added can be calculated by finding the slope of the line that runs through the two given points on the graph, (3, 5.5) and (8, 8).
Formula for slope =
Let,
.08 cents per ounce, because 2.40 ÷30 =.08
