Answer:

Step-by-step explanation:

$y = \frac{-1}{5}x - 4\\\\Plugin x = 0 , y = 0 - 4\\\\ y = -4\\\\(0 , -4)\\\\Plugin x = 5, y =\frac{-1}{5}*5-4 = -1-4=-5\\\\(5 , -5)\\\\Plugin x = -5, y =\frac{-1}{ 5}*(-5)-4=1 - 4 = -3\\(-5, -3)$

Plot the points(0 ,-4) , (5 , -5) and (-5 , -3 ) in the graph and join the points.

(1 point) 1. The height (in feet) and volume of usable lumber (in cubic feet) of 32 cherry trees are measured by a researcher. T

Thepotemich [5.8K]

Answer:

C. volume

Step-by-step explanation:

The response variable in this scenario would be the volume of the usable lumber. That is because this variable depends completely on the height of the cherry trees that are being measured. The higher that the cherry trees are the more volume can be expected to get from cutting these trees down. The opposite goes for trees that are smaller, they would decrease the total expected volume that will be received from the usable lumber since there would be less amount of tree to cut down.
