Question

Find a slope of the line that passes through (8,8) and (1,9)

Answer 1

The slope formula is

`m=(y_2-y_1)/(x_2-x_1)`

we can use this formula by introducing the values of the given points. In our case

`\begin{gathered} (x_1,y_1)=(8,8) \\ (x_2,y_2)=(1,9) \end{gathered}`

Hence, we have

`m=(9-8)/(1-8)`

It yields,

`m=(1)/(-7)`

hence, the answer is

`m=-(1)/(7)`
