Answer: 5
Explanation:
To find the slope of the line passing through the points (0,0) and (-8,-40), you can use the formula for slope:
\[ \text{Slope} = \frac{\text{Change in } y}{\text{Change in } x} \]
In this case:
Change in y = -40 - 0 = -40
Change in x = -8 - 0 = -8
Now, plug these values into the formula:
\[ \text{Slope} = \frac{-40}{-8} = 5 \]
So, the slope of the line passing through these two points is 5.
