Answer 1

The correct formula to find the slope of a line from two points \((x_1, y_1)\) and \((x_2, y_2)\) is:

\[
\frac{y_2 - y_1}{x_2 - x_1}
\]

So, the correct response is:

**y2−y1/x2−x1**
Start Fraction y subscript 2 baseline minus y subscript 1 baseline over x subscript 2 baseline minus x subscript 1 baseline End Fraction
