The tennis team is selling key chains as a fundraiser. If its goal is to raise at least $180, how many key chains must it sell at $2.25 each to meet that goal? Write and solve an inequality. A. 2.25k is greater than or equal to 180; k is greater than or equal to 100
B. 180k is greater than or equal to 2.25; k is greater than or equal to 80
C. 180k is greater than or equal to 2.25; k is greater than or equal to 150
D. 2.25k is greater than or equal to 180; k is greater than or equal to 80

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

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
