HELP QUICKLY The local softball field has a lemonade stand. The graph shows the amount of money in the cash register of the lemonade stand. (Image attached)

Questions: 1. What is the y-intercept?

2. What does the y coordinate of the y-intercept of the function represent?

3. What is the slope?

4. What does the slope of the function represent?

PLEASE HELP I REALLY NEED IT THANKS

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.

step-by-step explanation:

the answer is 40.
