Write the equation of the line in point-slope form given

m= 4 and the point (2,7)

• y + 7= 4(x - 2)

• y - 2 = 4(x - 7)

• y + 2 = 4(x + 7)

• y - 7= 4(x - 2)

Write the equation of the line in slope-intercept form that passes through the points (2, 5) (-2, -3)

• y = 2x - 4

• y = 2x + 1

• y = 2x - 5

• y = 2x - 2

Write the equation of the line.

• y = -2x - 4

• y = -1/2x - 4

• y = 2x - 4

• y = 1/2x - 4

Write a linear equation in slope-intercept form to model the situation:

Certapro Painters charge $16 per hour and a $250 flat fee

• y = 16x + 250x

• y = 250x + 16

• y = 250 - 16x

• y = 16x + 250

 $A\left(t\right)=900\left(0.85\right)^t$  

The equation above represents the value of a motor scooter t years after it was purchased. 

Which statement below is true?

• When new, the scooter cost $765

• When new, the scooter cost $900

• The scooter's value is decreasing at a rate of 85% each year

• The scooter's value is increasing at a rate of 85% each year

 $A\left(t\right)=900\left(0.85\right)^t$  

The equation above represents the value of a motor scooter t years after it was purchased. 

By how much is the value increasing or decreasing?

• The value is increasing by 85% each year

• The value is decreasing by 85% each year

• The value is increasing by 15% each year

• The value is decreasing by 15% each year
