Question

Jessica is selling books during the summer to earn money for college. She earns a commission on each sale but has to pay for her own expenses.
After a month from driving neighborhood to neighborhood and walking door-to-door, she figures out that her weekly earnings are approximately a linear function of the number of doors she knocks on.
She writes the equation of the function like this: E(x)=10x-35,where x is the number of doors she knocks on during the week and E(x) is her earnings for the week in dollars.

What does the slope of Jessica's function represent?

A. For each additional set of books she sells, her earnings will increase by $10
B.For each additional door she knocks on, her earnings will increase by $10
C.For each additional door she knocks on, her earnings will increase by $35
D. For each additional set of books she sells, her earnings will increase by $35

Answer 1

Start by making a graph xD

Answer 2

A graph is not needed, the question isn't being solved

Answer 3

You don't need to waste time and make a graph.

Answer 4

What is the slope here?

Answer 5

Multiple Choice doesn't need a graph

Answer 6

i dont know the slope i added everything the question
includes

Answer 7

You can identify it.

The equation is E(x)=10x-35

The slope (m) is the coefficient of x. So what is the slope?

Answer 8

B, because if x represents the doors and the numbers represent the money then for every door she knocked on that is 10 dollars

Answer 9

so the slope is 10

Answer 10

ok so its B then ?

Answer 11

My apologies Akshay i didn't realize you were typing

Answer 12

No all good (:

Answer 13

ok thanks guys!

Answer 14
