Question

Jake and Mike took some tests. Jake took x tests and scored 85 points in each test. The expression below shows Mike's total score.
85x - 15

What does the constant term of the expression represent?


A.The total score Mike earned
B.The total number of tests Mike took
C.The sum of Jake and Mike's total score
D.The difference between Jake and Mike's total score

Answer 1

What do you think the answer is?

Answer 2

idk thats why i asked the question

Answer 3

alright well if the expression is 85x - 15, can you tell me which is the slope and which is the constant?

Answer 4

ummm

Answer 5

alright well the slope is the term with the x in it. Usually you write equations for lines in the form
y = mx + b
where x is your independent variable, y is your dependent variable, m is your slope, and b is your constant term.

So in the case of y = 85x - 15
y is Mike's total score, x is the number of tests Jake or Mike take, 85 is the slope, and -15 is the constant

Answer 6

so the problem tells us that Jake scores 85 points on each test he takes

That means that the slope of 85 is the number of points earned per test.

So if Mike earns as many points as Jake per test (the slope of 85 means that he also gets 85 points per test), what does the minus 15 mean in the context of the problem?
