Y-4=2.5(x+3) in standard form

can someone please step by step explain??

-2.5x+y=11.5

Step-by-step explanation:

y-4=2.5(x+3)

distribute the 2.5 into the parenthesis

y-4=2.5x+7.5

add 4 to both sides

y=2.5x+11.5

now that it's in slope intercept form it will be easier to get into standard form

now subtract 2.5x from both sides

-2.5x+y=11.5

hope this helps you

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

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
