Write the point-slope form, slope-intercept form, and standard form of an equation for a line that passes through (5, 7) with slope -9.

Answer : Point slope form = y - 7 = -9(x-5)

Slope intercept form = y = -9x +52

Given :-

To Find :-

We know that point slope form of the line is,

→ y - y' = m(x - x')

where (x',y') is the point and m is the slope . On substituting the respective values, we have,

→ y - 7 = -9(x -5)

Now we know that slope intercept form of the line is,

→ y = mx + c

where m is the slope of the line and c is y intercept. On simplifying the above equation, we have,

→ y -7 = -9x +45

→ y = -9x +45+7

→ y = -9x + 52

I hope this helps.

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
