6). The ordered pairs all lie on the same line. Using the ordered pairs, write an equation of the line in the form y = mx + b. *
(2,-3) (6,-1) (0,-4) (14,3)

y = 1/2x - 4

Step-by-step explanation:

If you plot the first three coordinates you find the slope that is one half and your y-intercept is -4.

You can also figure it out without plotting it by finding the slope between the first two coordinates by finding the change of Y over the change of x and simplify it and you will get 1/2.

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
