Zane is a dangerous fellow who likes to go rock climbing in active volcanoes. One time, when he was 20 meters below the edge of a volcano, he heard some rumbling, so he decided to climb up out of there as quickly as he could. He managed to climb up 4 meters each second and get out of the volcano safely. Graph the relationship between Zane's elevation relative to the edge of the volcano (in meters) and time (in seconds).

the answer is below

Step-by-step explanation:

We must find the equation in order to make the graph.

According to the statement, the equation would be:

E = v * t - Ei

Being Ei (20) the initial elevation, t the elapsed time and the speed that is 4, we replace and we are left with:

 E = 4 * t - 20

Now, we must calculate the corresponding values:

E (0) = 4 * 0 - 20 = -20

E (1) = 4 * 1 - 20 = -16

E (2) = 4 * 2 - 20 = -12

E (3) = 4 * 3 - 20 = -8

E (4) = 4 * 4 - 20 = -4

E (5) = 4 * 5 - 20 = 0

If we graph we would have the attached image:
