Question

write in slope-intercept form an equation of the line that passes thorugh the given points.(1,2), ( -2, -1)

Answer 1

Determine the equation of line passing through two points.

`\begin{gathered} y-2=(-1-2)/(-2-1)(x-1) \\ y-2=-(3)/(-3)(x-1) \\ y-2=x-1 \\ y=x+1 \end{gathered}`

So equation of line is,

`y=x+1`
