Question

Find the slope of the line that contains these two points. (2, -5) and (7, -10)

Answer 1

$\sf Slope= \frac{y_2-y_1}{x_2-x_1}$

Where $\sf (x_1,y_1), (x_2,y_2)$ are the two points.

So

$\sf Slope = \frac{ -10-(-5)}{7-2}=\frac{-10+5}{7-2}=\frac{-5}{5}=-1$

So the slope of (2,-5) and (7,-10) was $\boxed{ -1}$

Answer 2

M=$\frac{y1-y2}{x1-x2}$=$\frac{-5-(-10)}{2-7}$=$\frac{5}{-5} =-1$
 Answer: slope is -1
