save you more offers a buy one/get one free item each week. customers who purchase only one of the items must pay the regular price. the limit is one deal per customer. is the relation (# sale items purchased, price) a function? why or why not?
a) it is a function because the input can be either 1 or 2 items, but the output will always be the same price.
b) it is not a function because the input can be either 1 or 2 items, but the output will always be the same price.
c) it is a function because the input will always be the same price, but the output can be either one or two items.
d) it is not a function because the input will always be the same price, but the output can be either one or two items.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

welcome ; )

step-by-step explanation:

i love jeffery and believe there is truth in tati and james' answers

step-by-step explanation:

yes i have heard the tea

i believe both

no, tati didnt over exaggerate

james might might idk and tbh dont rly care
