If you know a real-world problem is linear, such as the distance you travel when you go for a jog, you can graph the function and make some assumptions with only two points.
The slope of a function is the same as the rate of change for the dependent variable ( y ). For instance, if you’re graphing distance vs. time, then the slope is how fast your distance is changing with time, or in other words, your velocity.
