Tell whether the relationship is a proportional relationship. Explain why orwhy not.

A graph is proportional if a straight line can be drawn through the points and it crosses through the origin. A proportional relationship for objects occurs when the object number increases or decreases and a value of the object increases or decreases at a consistent rate.

1. C

A line can be drawn through the points, however it would not cross through the origin.

2. A

As the number of hours increases by 1, the dollars earned increases by $12.50. This increase in dollars earned is consistent across all increases in hours.

3. 4 gallons of milk for $13.16, 5 gallons of milk for $16.45, 9 gallons of milk for $29.61

If we check all of the options by multiplying the number of gallons by the given price per gallon, the following relationships are proportional to the original.

Hope this helps!! :)

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

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.
