• 

Which equation represents a line with slope 4 and goes through the point (5, -2)?

• y = 4x + 22

• y = 4x – 22

• y = -4x + 22

• y = -4x – 22

Which equation represents a line that passes through the point (-3, 2) and is perpendicular to

y = 5x – 2?

• y – 2 = 5(x + 3)

• y – 3 = 5(x + 2)

• y – 2 = -⅕(x + 3)

• y + 2 = -⅕(x – 3)

A zoo keeper thinks there is a problem with the Mole-Rat population at the zoo. He starts keeping track of the animals in the tunnels. 7 days into his monitoring he counts 120 mole rats, 13 days in he counts 108. If the relationship between the number of days d and the amount of mole rats, r is linear, which equation models this relationship?

• r – 120 = -134(d – 7)

• r – 7 = 2(d – 120)

• r – 120 = -2(d – 7)

• r – 120 = 134(d – 7)
