Question

5.Find the equation ofthe line:through: (0, -3) and (-1,-5)

Answer 1

first, we will find the slope

`m=(-5-(-3))/(-1-0)=(-5+3)/(-1)=(-2)/(-1)=2`

so, the slope is m = 2

now the equation of the line is

`\begin{gathered} y-(-3)=m(x-0) \\ y+3=2x \\ y=2x-3 \end{gathered}`

so, the equation of the line is y = 2x -3
