This graph shows the temperature of a room over time. how many °f does the temperature of the room increase by every 1 min? enter your answer in the box. °f

Solution:

Graph of temperature of a room(°F) and time(T) is given in the graph.

When Time increases temperature of a room also increases.

It means time is in directly proportional to temperature.

We can Find  equation of line using two point slope formula.

The line passes through (0,65) and (20,75).

X coordinate = Time, Y coordinate = Temperature

Equation of line passing through

Equation of line passing through (0,65) and (20,75) is given as:

⇒

When t=1 i.e x=1

1 - 2 y + 130 = 0

2 y = 131

y = 65.5°F

The temperature increases by 0.5° C with every increase of time by 1 minute.
