Question

What is the slope of the line passing through the following points: `(7/10,-1) , (-1/5, -1/5)`?

Answer 1

Slope `m=-2/3`

Explanation:

Given -

`x_1=7/10`
`y_1=-1`
`x_2=- 1/5`
`y_2=- 1/5`

Slope `m=(y_2-y_1)/(x_2-x_1)=(-1/5-(-1))/(-1/5-7/10)=((-1+5)/5)/((-5-7)/10)=(4/5)/((-12)/10)`
`=4/5 -:(-12)/10=4/5 xx 10/(-12)=-40/60=-2/3`
