McKenzie delivers coupons to her neighborhood. This week she has 553 coupons to deliver. If she wants to give 7 coupons to each neighbor, which equation can be used to find the number of neighbors, n, to whom McKenzie can give coupons?

Number of neighbors to whom McKenzie can give coupons = 79

Step-by-step explanation:

Coupons to deliver this week = 553

Coupons delivered to each neighbor = 7

which equation can be used to find the number of neighbors, n, to whom McKenzie can give coupons?

Let

n = number of neighbors to whom McKenzie can give coupons

n = Coupons to deliver this week / Coupons delivered to each neighbor

= 553 / 7

= 79

n = 79 neighbors

Number of neighbors to whom McKenzie can give coupons = 79

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
