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

stethere all not eveanp-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
