Answer:
Slope of line = ![\frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D)
Step-by-step explanation:
We have given two points,
(-4 ,-8) and ( - 18 , -10)
We need to find the slope of line passing through these two points.
i.e slope of line = ![\frac{y_{2} - y_{1} }{x_{2} - x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%20%20%7D%7Bx_%7B2%7D%20-%20x_%7B1%7D%20%20%7D)
Here y₂ = -10 , y₁ = -8 , x₂ = -18 and x₁ = -4
Hence,
slope of line =
= ![\frac{-2}{-14}](https://tex.z-dn.net/?f=%5Cfrac%7B-2%7D%7B-14%7D)
Slope of line = ![\frac{1}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B7%7D)
The height of the candles when they first burn down to the same height is 10 cm
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
Let y represent the height of the candle after x hours.
For the first candle:
y = -(5/6)x + 15
For the second candle:
y = -(5/2)x + 25
To have the same height:
-(5/6)x + 15 = -(5/2)x + 25
x = 6 hours
y = -(5/2)(6) + 25 = 10 cm
The height of the candles when they first burn down to the same height is 10 cm
