Linear Equations Problems

Which equation best represents the relationship between x and y in the table shown?

• y= 5x+5

• y=1/5x+5

• y=15x+5

• y=10x+5

Find the equation of the line in slope-intercept form.

• y = - 1/4x - 3

• y = 1/3x + 3

• y = - 1/4x + 2

• y = 1/3x -3

Derrick started up a charity for the local animal shelters. He started selling handmade dog leashes for $5. It cost him $120 to get the supplies to make the leashes. Write an equation for the amount of money he raises, A, if he sells x amount of leashes.

• A = 120 + 5x

• A = 120x + 5

• A = -120 + 5x

• A = 120 - 5x

Write an equation in slope-intercept for of the line between the points: (-2, 8) and (3, -12)

• y = -(4/5)x + (32/5)

• y = -4x

• y = -4x + 16

• y = 4x

Identify the y-intercept for the function:
y=-3x

• -3

• 0

• 1

• -1

Find the slope between the points
