Use two ordered pairs (0,22) and (2000,6) to write a prediction equation and choose the correct option:
O y = 0.008x + 22
O y = 0.008x - 22
Oy -0.008x + 22
O y = -0.008x - 22
H

Answer 1

y -0.008x + 22

The grap- is a line with a negative incline. By that alone you can dismiss answers a and b.

The intersection with the y-axis is at (0,22)..

Since it starts at 22 degrees Celsius, which is a positive number., you know you have enough to choose the right answer, which must the the third one.
