11) $y = 12x + 22$

10) $y = 5x - 4$

9) $y = -2x + 1$

8) $y = 2x + 9$

7) $y = 12x - 28$

6) $y = 1\frac{1}{3}x + 2$

5) $y = 4x - 2$

4) $y = x$

3) $y = 1\frac{2}{5}x - 7$

2) $y = 2x - 4$

1) $y = \frac{2}{3}x - 8$

Step-by-step explanation:

12)

y - 4 = −(x - 4)

y - 4 = −x + 4

+ 4 + 4

__________

$y = -x + 8$

_______________________________________________

11)

y + 2 = 12(x + 2)

y + 2 = 12x + 24

- 2 - 2

____________

$y = 12x + 22$

_______________________________________________

10)

y - 1 = 5(x - 1)

y - 1 = 5x - 5

+ 1 + 1

_________

$y = 5x - 4$

_______________________________________________

y - 5 = −2(x + 2)

y - 5 = −2x - 4

+ 5 + 5

___________

$y = -2x + 1$

_______________________________________________

y - 5 = 2(x + 2)

y - 5 = 2x + 4

+ 5 + 5

__________

$y = 2x + 9$

_______________________________________________

y + 4 = 12(x - 2)

y + 4 = 12x - 24

- 4 - 4

____________

$y = 12x - 28$

___ _____

−3 −3

$y = 1\frac{1}{3} + 2$

_______________________________________________

4x - y = 2

-4x - 4x

_______

−y = −4x + 2

$y = 4x - 2$

_______________________________________________

2x - y = 4

-2x - 2x

_______

−y = −2x + 4

$y = 2x - 4$

_______________________________________________

2x - 3y = 24

amm1812

The down payment is the lower of sale price and appraised value less the loan amount. It is not the same as the borrower's cash outlay if some of that outlay is used for settlement costs. Financing settlement costs does not affect the down payment.
