How I can answer this question, NO LINKS, if you answer correctly I will give u brainliest!

See the image and also look at explanation! Please give me brainliest!!!

Step-by-step explanation:

What I did here is I put the information we have into a linear equation in the form of y=mx+b, or slope-intercept form. m is slope and b is y-intercept

when the amount of time(seconds) was 0, he was 20 feet below the volcano. So, I plotted the point (0,-20). The red dot on the attached image.

Now, every second, you move up 4 meters, so you have a slope of 4.

On the graph, you would move up four units and right one unit, as shown by the blue point on the attached image.
