The correct formula to find the slope of a line from two points \((x_1,y_1)\) and \((x_2,y_2)\) is:
\[ \text{Slope} = \frac{y_2 - y_1}{x_2 - x_1} \]
So the correct response is:
\[ \frac{y_2−y_1}{x_2−x_1} \]
This formula calculates the change in the y-values divided by the change in the x-values, which gives the slope of the line.
