To get the equation of a line, you can use the following:
y - y1 = m (x - x1)
Where:
- m is the slope (2)
- y1 is the y coordinate of a point (1, -5)
- x1 is the x coordinate of the same point (1, -5)
Just substitute in the values:
y - y1 = m (x - x1)
y - (-5) = 2(x - 1) <em>( - - 5 = + 5 )</em>
y + 5 = 2(x - 1)

Answer:
B. y + 5 = 2(x - 1)
Using the average rate of change, it is found that the average rate is of:
(1) 2.1 °F per minute
<h3>What is the average rate of change of a function?</h3>
It is given by the <u>change in the output divided by the change in the input</u>.
In this problem:
- At 15 minutes, the temperature was of 90ºF.
- At 45 minutes, the temperature was fo 153ºF.
Hence, in 30 minutes, the temperature increased 63ºF, hence the rate is given by:
r = 63/30 = 2.1 °F per minute.

Answer:
36 pi (C)
Step-by-step explanation:
The area of a circle is pi * r^2
Because the radius is 6, the area is pi6^2 = 36 pi
