Final Answer:
The slope of the line passing through the points (0,20) and (1,80) is 60.
Step-by-step explanation:
To find the slope (m) of a line given two points (x1, y1) and (x2, y2), you can use the formula:
![\[ m = \frac{{y2 - y1}}{{x2 - x1}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/wtfixik7oq2rrogr9hxwjyoxxqf1dehor8.png)
In this case, the points are (0,20) and (1,80). Substituting the values into the formula:
![\[ m = \frac{{80 - 20}}{{1 - 0}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/q9k5iniiz3ll6evc51nv324aky85znscvw.png)
![\[ m = \frac{{60}}{{1}} \]](https://img.qammunity.org/2024/formulas/mathematics/high-school/7tz50txkaiynts86k8brqdk4g1bsc7018w.png)

Therefore, the slope of the line is 60.
This means that for every unit increase in the x-coordinate, the corresponding y-coordinate increases by 60 units. In practical terms, if you move one unit to the right on the line, the y-value increases by 60. This slope can also be interpreted as the rate of change between the two variables.
