Write the equation -11x+9y=-12 in slope intercept form. what are the slope and y intercept?

Step-by-step explanation:

first solve for y (or x) I chose y.  

-11 + 9y = -12

(-11) - (-12) =  1

9y = 1

9/1 = 1

y=1, now for x.

-11x + 9 = -12

-12 - 9 = -21

-11x = -21

-21/-11 = -32

x = -32.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
