The original cost of a cell phone is x dollars. The phone is on sale for 35% off. Write a simplified expression for the sale cost.

.65x

Step-by-step explanation:

the cost of the phone is x

The discount is 35%

.x35

Subtract the discount from the price

x - .35x

.65x

this is the new price

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
