I am in need of help !!

Step-by-step explanation:

Hello! I see your teacher is a Harry Potter fan. Anyways,

1) The y-intercept is when you plug x as 0 or it's when the line crosses the y axis. The easiest way to find the y-intercept is to look at the graph and see where the graph starts off from the y axis.

We can see that the line starts off from (0,0) so the y-intercept is (0,0).

In this case, the y-intercept represents the initial income when you haven't start working yet.

2) The formula for slope is y2-y1/x2-x1. We can find any two points on the line to do this equation. Lets take (0,0) and (2,30).

Let's now plug in the y, 30 - 0

And then the x, 2 - 0

Together they are 30 - 0/ 2 - 0

Or 30/2 = 15.

The slope is 15

In this case, the slope represents the amount of income earned per hour/every hour.

Y intercept is 0, slope is 15

Step-by-step explanation:

Hi! This is 2023elliottsg I just now found your question, the y intercept is 0 because the line meets the y axis at (0,0)

the slope is 30/2 which simplifies to 15 because from point (4,60) it rises 30 and runs 2 over to point (6,90)

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
