and (x2,y2)
?(1 point)
Responses

y2+y1x2+x1
Start Fraction y subscript 2 baseline plus y subscript 1 baseline over x subscript 2 baseline plus x subscript 1 baseline End Fraction

y2−y1x2−x1
Start Fraction y subscript 2 baseline minus y subscript 1 baseline over x subscript 2 baseline minus x subscript 1 baseline End Fraction

x2−x1y2−y1
Start Fraction x subscript 2 baseline minus x subscript 1 baseline over y subscript 2 baseline minus y subscript 1 baseline End Fraction

y2y1−x2x1

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:

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

This option corresponds to:

**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

So, the answer is the second option.
