What is the answer to B at the bottom?

Step-by-step explanation:

A) For the city of Everettt, y-intercept  represent the number of chrome books they started with.

y - intercept = 550

Everett started the 2016 year with 550 chrome books

B)  y = 50x + 300

Explanation: They stared with 300 books at 2016. This will be the y-intercept

Rate of change = 50 books per year which will the slope

m = 50 and b = 300

y = mx + b

y = 50x + 300

Hint:  y- intercept is where x-coordinate =0

1 and 2

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
