Given the graph of a line
As shown, the line passes through the points (0, -2) and (1, 2)
the slope of the line will be as follows:
![slope=(rise)/(run)=(y_2-y_1)/(x_2-x_1)=(2-(-2))/(1-0)=(2+2)/(1)=4](https://img.qammunity.org/2023/formulas/mathematics/college/w7vxxm7qhygv9wsxi7rple4bkpf4hvnby2.png)
the meaning of this slope:
The rate of change of the line = 4
That means y increases (4) units when (x) increases 1 unit
