Erin and jamie are collecting shells while the tide is out. erin has 27 shells, and she has 9 more than jamie. write and equation for this situation and find how many shells jamie has collected. a. 27 = j + 9; jamie collected 18 shells b. 27 = j – 9; jamie collected 36 shells c. 27 + 9 = j; jamie collected 36 shells d. 27 = j + 9; jamie collected 36 shells

A.

Erin's total minus 9 gives us Jamie's total. This means Erin's total equals Jamie's total plus 9. This leads us to the conclusion that 27 (E's total) = j + 9 (the difference). We also know from the first phrase that E - 9 = j, meaning 27 - 9 = j, so j = 18.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
