Pre-algebra 8th grade flvs (mark brainiest/ 30 points)
the graph below shows the height an elevator travels, y, in x seconds:

what is the rate of change for the relationship represented in the graph?
50
25
1/25
1/50

25

Step-by-step explanation:

I'm not in 8th grade... but I am quite smart.

Look at the graph. Each point goes up 25. It starts at the origin, then 25, 50, 75, 100. In other words, 50 = 25 + 25, 75 = 25 + 25 + 25, and 100 = 25 + 25 + 25 + 25.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

to determine the unit cost your would divide the total cost by the number sold.
