Acoffeehouse charges a flat rate, r, for each hour customer wants to use the internet. enter an equation to express the total cost, c,to use the internet at the coffeehouse for t hours.

c=rt is the equation to express the total cost c to use the internet at the coffeehouse for t hours.

Step-by-step explanation:

Given A coffeehouse charges a flat rate, r for each hour customer wants to use the internet. we have to write the equation to express the total cost c to use the internet at the coffeehouse for t hours.

Charges of internet per hour = r

Total hour = t hours

Hence, Cost = (Charges per hour)(Total hours)

                     =

∴ c=rt

which is the linear equation to express the total cost c to use the internet at the coffeehouse for t hours.

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
