Question

4. ( -1 , 3 ) and ( 4, -7 ) 5. ( 3, 2) and (6, 5)

Answer 1

`\begin{gathered} \text{slope}=m=(y_2-y_1)/(x_2-x_1) \\ \end{gathered}`

Therefore,

4.

`\begin{gathered} (-1,3)(4,-7) \\ \text{slope}=(-7-3)/(4+1) \\ \text{slope}=(-10)/(5)=-2 \end{gathered}`

5.

`\begin{gathered} (3,2)(6,5) \\ \text{slope}=(5-2)/(6-3) \\ \text{slope}=(3)/(3) \\ \text{slope}=1 \end{gathered}`
