To determine the slope of a line in a coordinate plane, you need two points on the line. The slope (m) is calculated using the formula:
\[ m = \frac{y_2 - y_1}{x_2 - x_1} \]
Where \((x_1, y_1)\) and \((x_2, y_2)\) are the coordinates of the two points.
Once you have the coordinates of two points, plug them into the formula to find the slope. If you provide the coordinates of the points on the line, I can help you calculate the slope.
