Answer:
The equation shows the temperature over time will be:
Hence, option (C) is correct.
Step-by-step explanation:
We know that the slope-intercept form of the line equation is
where m is the rate of change or slope and b is the y-intercept
- Let 'y' be the temperature
- Let 'x' be the time in the hour
Given that one very cold morning, it was -7°F.
Thus, the y-intercept = b = -7
Given that as the day went on, the temperature rose 3 degrees each hour.
Thus, the rate of change = slope = m = 3
Thus, substituting m = 3 and b = -7 in the equation
Therefore, the equation shows the temperature over time will be:
Hence, option (C) is correct.
