Answer:

A: y=2x+4

B. 34° Celsius

Explanation:

A:

Since the temperature goes up at a steady rate of 2 degres per minute, we can assume that 2 is our slope. Since the graph shows us that 4 is the y-intercept, we can substitute both the slope and y-intercept into the equation of a line, or y=mx+b. (m is our slope and b is our y-intercept.)

Doing so gives you:


y = 2x + 4

B.

Using the above formula (y=2x+4), we can substitute x with 15 (since x is the minutes that pass).

Doing so gives you y=30+4, the sum of which is 34.

Therefore, the answer should be 34° Celsius.
