Answer 1

2

Explanation:

Answer 2

The slope of line p is 3.

The slope of line q is -3.

Explanation:

Points on line p =
`(x_1,y_2),(x_2,y_2):(1,-1), (0.-4)`

Slope of line p ,m=
`(y_2-y_1)/(x_2-x_1)`

`m=(-4-(-1))/(0-(1))=3`

The slope of line p is 3.

Points on line q =
`(x_1,y_2),(x_2,y_2): (0,2), (1,-1)`

Slope of line q ,m'=
`(y_2-y_1)/(x_2-x_1)`

`m'=(-1-2)/(1-0)=-3`

The slope of line q is -3.
