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.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

for future students the answer is b
