The glee club is selling cupcakes at a local fair. they must pay $20 to rent a booth and they are selling cupcakes for $2 each. graph their profit or loss in dollars, against the number of cupcakes they sell.

label the y-axis as finances (or a synonym)

create intervals from -$20(I'd advise in 10's)

label the x-axis as cupcakes sold

create intervals from 0(I'd advise in 5's)

the graph will start at (0,-20)

it should follow the slope of 2

(i.e. - for each 5 cupcakes, $10)

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

what’s the question?
