Answer 2

I saw 420 and stopped reading, ill do the math tho <333

Answer 3

Ok, what does this problem give us?

Answer 4

x is # of magazines, y is profit as stated in the problem

Therefore, 60 magazines, $220 profit can be written as (60,220). Likewise, 100 magazines, $420 profit means (100,420)

Use the slope formula on these two points to get m, the slope

From there, use the point slope formula

y - y1 = m(x-x1)

Judging by the answer choices, they want you to use (60,220) as (x1, y1). Plug in this, along with your slope from earlier, to get the complete formula.

Answer 5

I think it is like
220=60x+b and 420=100x+b

Answer 6

B?

Answer 7

yes........

Answer 8

No its not B

Answer 9

@astrid1

Answer 10

60 and 100 are not slope values.

(60,220) and (100,420)
Let’s let (x1, y1) be (60,220)
And (x2,y2) be (100,420)

m = (y2-y1) / (x2 - x1) = (420 - 220) / (100 - 60)

Answer 11

oh ty so d?

Answer 12

(420 - 220) / (100 - 60) = 200/40 = 5

So your slope should be 5 not 2, so it cannot be D
