The 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:
\[ \text{Start Fraction y subscript 2 baseline minus y subscript 1 baseline over x subscript 2 baseline minus x subscript 1 baseline End Fraction} \]
