I think the independent variable is the number of people and the dependent is the wait time. I see it as the wait time DEPENDS on how many people are in line. This one is kinda confusing tho
Your answer would be 4x-7=-3(3+4x) because it only has one solution which is x= -1/8
The slope of the line is 5/1 because the number by the x is always your slope and it is always to be announced as a fraction so you add 1 as the denominator if there isn’t already a denominator.
Answer:
Sorry I could only find the answer to the second part.
y=56x
