Question

Suraj took a slice of pizza from the freezer and put it in the oven. The pizza's temperature (in degrees celsius) as a function of time (in minutes) is graphed. The graph of the line is y = 8x - 6. How long did it take the pizza to reach 0 degrees celsius?

Answer 1

To determine when the pizza reached 0 degrees Celsius, we solve the equation y = 8x - 6 with y set to 0. It took 0.75 minutes for the pizza to warm up to 0 degrees.

Step-by-step explanation:

The student's question is about finding the time it took for Suraj's pizza to reach 0 degrees Celsius using the given linear equation y = 8x - 6, which represents the temperature of the pizza as a function of time.

To find the time when the temperature reached 0 degrees, we set y to 0 and solve for x:
0 = 8x - 6. Adding 6 to both sides gives us 6 = 8x, and then dividing both sides by 8 gives x = 0.75.

Therefore, it took 0.75 minutes for the pizza to reach 0 degrees Celsius.
