Answer:
<em>h</em><em> </em>= 15 - 1.5<em> </em><em>t</em>
Step-by-step explanation:
In this example, I made <em>h</em><em> </em>height.
For this situation, you would use <em>y</em><em>=</em><em>mx</em><em>+</em><em>b</em><em>.</em>
If we use this formula, <em>m</em><em> </em>would be slope. 1.5 is the slope and we are <em>decreasing</em> the size of the candle, which makes -1.5.
<em>x</em><em> </em>would be <em>t</em> because that's the independent variable.
Since the initial height was 15 inches, 15 would be our starting point or y-intersept, which is <em>b</em><em>.</em>
So if you put that together, you get <em>h</em><em>=</em><em>-1.5t</em><em>+</em><em>15</em><em>.</em>
You can rearrange that to the answer above.
