Can someone please help me with math

3 - B

4 - D

Step-by-step explanation:

Hey There!

they are asking for the slope in slope intercept form

y = mx + b

where m = slope and b = y intercept

The slope is change in y over change in x

as y goes up 4 x goes up 2

4/2=2 so the slope (or m ) is 2

The y intercept is at point (0,-4)

So the y intercept (or b) is -4

now we add everything together and get that the equation of the line is

y=2x-4

for 4

the best rule is D 2n+2

Why? because the rate of change is 2

and the y intercept is at (0,2) so the best rule would be 2n+2

Question 3 is B

Step-by-step explanation: Get two points from the graph like (2,0) and (4,4) and use m=change of y over change of x . 4/2 is simplified to 2 . Therefore , B is correct

step-by-step explanation:

the options are kind of confusing. i can tell you what i see going on here when i look at the graph.

the class and exam medians are closely related, and it looks like the low outlier on the exam did pull the median lower. [tex][/tex]
