Question

The temperature at 1:00 p.m. The temperature at 1:00 p.m. on Tuesday was -13°C. There was an increase of 6º per

hour starting at 1:00 p.m. Which of the following best represents the Celsius
temperature n hours after 1:00 p.m. on Tuesday?
A. -13 + bn
B. -13 - 6n
C. -13n + 6
D. -13n - 6

Answer 1

• Rate of change=m=6°C
• Initial temp=b=-13°C

So

Equation in slope intercept form

• y=mx+b
• y=6n+(-13)
• y=6n-13

Option A
