Question

The equation y = 12 - 0.2x shows the amount of candle that is left (in ounces) after

burning for x hours. What is the y - intercept for the function, and what does it represent

Answer 1

The y-intercept is 12.

It represents the original length of the candle.

Explanation:

y = 12 - 0.2x

y = 0.2x + 12

y = mx + b

b is the y-intercept.

b = 12

The y-intercept is 12.

It represents the original length of the candle.
