Answer:

y + 1 = 4(x - 2)

y = 4x + 11

8x - 2y = 6

Following equations are parallel to the graph 4x - y = 6, because their slopes are equal (4).

y + 1 = 4(x - 2)

y = 4x + 11

8x - 2y = 6

Tuition for one year at the community college Sean would like to attend is about $8,880. Sean plans to save money each month for
REY [17]

First make an equation then solve for the variable.

8,800 is the end goal so that is what it is going to equal

Since his parents are contribuating 6,000 we can add that as a constant

Now it says in 2 years but it askes us in months so we times 2 by 12 to get 24 months he will be saving.

Now it is asking us how much he should save per month be we don't know that so that is our variable.

8,800 = 24x + 6,000

Solve

8,800 - 6,000 = 24x

2800/24 = x

116.67 = x (rounded for currency)

Sean would have to save $116.67 a month in order to pay for the community college
