Sam's family has a new car that indicates the temperature inside the car. He noticed that, with the air conditioner on, the temperature in the car changed −2°F each minute for 5 minutes. What integer represents the effect that the air conditioner had on the car's temperature during this time? A) 2°F

B) −2°F

C) 10°F

D)−10°F

-10

Step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
