Y=-(3/5)x+2 in standard form

  3x +5y = 10

Step-by-step explanation:

Multiply by 5 to make all numbers integers. Then add the opposite of the x-term to separate variable terms from the constant.

  5y = -3x +10 . . . . multiply by 5

  3x +5y = 10 . . . .  add 3x

Comment on standard form

The standard form of a linear equation is ...

  ax +by = c

where a, b, c are mutually prime integers, and a≥0. If a=0, then b>0.

0 is its x and y coordinate

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
