Question

what is the slope formula?
a. \\(\frac{y_2 + y_1}{x_2 + x_1}\\)
b. \\(\frac{x_1 - x_2}{y_2 - y_1}\\)
c. \\(\frac{y_2 - y_1}{x_2 - x_1}\\)
d. \\(\frac{x_2 - x_1}{y_2 - y_1}\\)

Explanation:

The slope of a line between two points $(x_1, y_1)$ and $(x_2, y_2)$ is defined as the ratio of the change in the y-values (rise) to the change in the x-values (run). This corresponds to the formula that calculates the difference of the y-coordinates divided by the difference of the x-coordinates in the same order.

Answer:

C. $\frac{y_2 - y_1}{x_2 - x_1}$
