Question

How do I calculate slope of the line that passes through the labeled points on the given graphs below?

Answer 1

Just suppose one of the points as `(x_1,y_1)` and the other as `(x_2,y_2)`
The slope of line passing through `(x_1,y_1)` and `(x_2,y_2)` is
`m=(y_2-y_1)/(x_2-x_1)`
Where, `m` is your required slope.

I will do the first one and leave the rest for your practice.
`(x_1,y_1)=(3,3)`
`(x_2,y_2)=(-2,1)`
We have,
`m=(y_2-y_1)/(x_2-x_1)`
`m=(1-3)/(-2-3)`
`m=(-2)/-5`
`:. m=2/5`

Hope this helps :)
