2. Peter's mom wrote down the number of items purchased every week at the grocery store as well as the amount of money she spent. She transferred this information onto a graph. If there are only
three people in the family, what would be a reasonable domain for this situation?
A. {0, 10, 5, 13}
B. {4, 5, 6, 7}
C. {49, 59, 64, 77}
D. {735, 885, 832, 1,001}

Step-by-step explanation:

A

Step-by-step explanation:

36

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
