Question

I have to find the slope of the line but i dont understand how.

Answer 1

From the given figure,

We have two points for the given line as,

`(1,0)\text{ and (0, -3)}`

So, the equation for the line is given as,

`\begin{gathered} (y-y_1)=(y_2-y_1)/(x_2-x_1)(x-x_1) \\ y-0=(-3-0)/(0-1)(x-1) \\ y=(-3)/(-1)(x-1) \\ y=3(x-1) \\ y=3x-3 \end{gathered}`

Hence, the equation of the given line is y=3x-3
