Question #116ad

Answer 1

The equation of the line is `13x +9y = -29`

Explanation:

The slope of the line is `m=(y_2-y_1)/(x_2-x_1)= (4+9)/(-5-4) = -13/9`

The equation of the line passing through `(4,-9)` is

`y-y_1=m(x-x_1)`

`y+9 = -13/9(x-4)`

`9y+81= -13x +52`

`13x +9y = -29`

graph{13x+9y=-29 [-20, 20, -10, 10]}
