Elsa got a prepaid debit card with $15 on it. For her first purchase with the card, she bought some bulk ribbon at a craft store. The price of the ribbon was 7 cents per yard. If after that purchase there was $12.83 left on the card, how many yards of ribbon did Elsa buy?

0.31 yards of ribbon

Step-by-step explanation:

15 - 12.83 = 2.17

7x = 2.17

7/7x = 2.17/7

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn
