Question

You buy a brand new wax candle that stands 6 inches tall. Knowing that the rate at which the wax melts is approximately 1/100 of an inch per minute, write a linear equation that could model this situation.

Answer 1

y=-1/100x+6 or y=-1x+600

Explanation:

6 inches is the Y intercept (600,0) if measuring by 1/100 or (6,0)

Since the wax is melting, the slope is going to be negative

y=mx+6 or y=mx+600 either is fine and would yield the same results

y=-.01x+6, y=1/100x+6 or y=-1x+600

To explainn why 6 and 600 are both fine, 6 is measuring with full inches while the 600 is measuring with .01 inches. One graph will be full numbers while the other will be decimals.
