HURRY The dot plots below show the scores for a group of students who took two rounds of a quiz:
Which of the following inferences can be made using the dot plot?

A: The range of each round is the same.
B: There is no overlap between the data.
C: Round 1 scores were higher than round 2 scores.
D: Round 2 scores were lower than round 1 scores.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
