Question

Y- y Use the slope formula to find the X-X slope. 1. (3,-1) and (-3,5) 2. (4, -2) and (2,-3) 3. (3,-1) and (-6,-4)

Answer 1

$\text{slope}=m=\frac{y_2-y_1}{x_2-x_1}$

1. (3, -1)(-3, 5)

$\begin{gathered} \text{slope}=m=\frac{y_2-y_1}{x_2-x_1} \\ \text{slope}=\frac{5+1}{-3-3} \\ \text{slope}=\frac{6}{-6} \\ \text{slope}=-1 \end{gathered}$

2. (4, -2)(2, -3)

$\begin{gathered} \text{slope}=\frac{-3+2}{2-4} \\ \text{slope}=\frac{-1}{-2} \\ \text{slope}=\frac{1}{2} \end{gathered}$

3. (3, -1)(-6, -4)

$\begin{gathered} \text{slope}=\frac{-4+1}{-6-3} \\ \text{slope}=\frac{-3}{-9} \\ \text{slope}=\frac{1}{3} \end{gathered}$
