slope $= 3$ $=3$

The points are:
$(3, 5) = x_{1}, y_{1}$ $(3,5) = color(blue)(x_1,y_1$

$(1, - 1) = x_{2}, y_{2}$ $(1,-1) = color(blue)(x_2,y_2$

The slope is calculated using formula:

slope $= \frac{y_{2} - y_{1}}{x_{2} - x_{1}}$ $=(y_2-y_1)/(x_2-x_1)$

$= \frac{- 1 - 5}{1 - 3}$ $=(-1-5)/(1-3$

$= \frac{- 6}{- 2}$ $=(-6)/-2$

slope $= 3$ $=3$

What is the slope of the line passing through the following points: (3,5) ; (1, -1)(3,5);(1,−1)(3,5) ; (1, -1)?
