Question

HELLLLLLLLLLLLP!!!! I NEED HELP I THINK I KNOW IT BUT I NEED TO CHECK!!

Which graph could be used to show the situation described?

The temperature starts at 0º and decreases by 12º every hour.

Answer 1

The second graph

Explanation:

The only graphs that start at 0 are the first and second graphs.

The first graph decreases by 1 degree every hour; this is not the correct graph.

The second graph decreases by 60 degrees over 5 hours; this is a change of 60/5 = 12 degrees every hour. This is the correct graph.

Answer 2

It's that second graph. Starts at (0,0) and slope = -12
So it goes ....
(0,0)
(1,-12)
(2,-24)
(3,-36)
(4,-48)
(5,-60)
