Identify the equation that has a slope of -3 and a y-intercept of -9. y = 3x + 9

y = -9x - 3

y = 9x + 3

y = -3x - 9

y = -3x - 9

Step-by-step explanation:

y=mx+b

^ That is the slope intercept form

M - Slope

Y - Y value

X - X value

B - Y intercept

We know that the slope is -3 and the y intercept is -9, so the equation should be:

y = -3x - 9 (The fourth answer)

10 you would take 50/ .2

step-by-step explanation:

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
