Slope is y1-y2 over m1-m2 (rise over run). The first ordered pair is -2 (m1) and 11 (y1). We then subtract the second ordered pair (4 (m2) and -4 (y2)) from the first.

11 - (-4) = 11 + 4 = 15

-2 - 4 = -6

Remember, slope is rise over run (y over x), so the slope is 15/-6. Now, we must simplify. 15/-6 = 5/-2

Dean went wrong because he thought that slope was run over rise (x over y). If he had switched the two numbers, his answer would have been correct.

It takes 4 pounds of grapes to make 1 pound of raisins. How many pounds of grapes would you need to make 3000 pounds of raisins?

ryzh [129]

4:1
(grapes);(rasins)

4:1
x:3000
so you then cross multiply
1·x=4·3000
multiply,
x=12000

so the answer is it takes 12000 pounds of grapes to make 3000 pounds of raisins
