Question

The temperature was 56 degrees this morning, but dropped one degree per hour through the rest of the day. The equation is y=-x+56. You may usey=56-x . They are the same equation. Use x-values: 0, 5, and 10.

Answer 1

At x=0

• y=56-0
• y=56°C

At x=5

• y=56-5
• y=51°C

At x=10

• y=56-10
• y=46°C
