Answer: C: -2.5

Step-by-step explanation:

When looking at the graph we see that the temperature (y-axis) starts at 80 degrees. To find the slope, or how much it decreases and how often, we find the difference between 80 and the temperature it dropped to which is 77.5 . We also see it dropped this much after 1 hour which means each hour it drops -2.5 degrees so the correct answer is C.

Viefleur [7K]

Answer:

x = -7

Step-by-step explanation:

First we find the slope using

m = ( y2-y1)/(x2-x1)

   = ( -8 - 5)/( -7 - -7)

   = (-8-5)/(-7+7)

   = -13/0

This means the slope is undefined and the line is vertical

Vertical lines are in the form

x= constant and the constant is the x value of the points

x = -7
