Answer 1

13.

The equation of line is
`y=x+13`

Explanation:

Points:

`(7,20),(-2,11)`

Slope of line:

`m=(y_2-y_1)/(x_2-x_1)\\\\m=(11-20)/(-2-7)\\\\m=(-9)/(-9)\\\\m=1`

Point slope-equation:

`(y-y_1)=m(x-x_1)\\\\(y-20)=1(x-7)`

Using distribution.

`y-20=(1* x)+(1*-7)`

`y-20=x-7`

Adding 20 to both sides.

`y-20+20=x-7+20\\\\y=x+13`

The equation of line is
`y=x+13`
