Here, we want to graph the line

To do this, we need to get the y-intercept and the x-intercept

The general equation form is;


y\text{ = mx + b}

M is the slope while b is the y-intercept

Let us write the equation in the standard from;


y\text{ = -3x-1}

The y-intercept is -1

So we have the point (0,-1)

To get the x-intercept, set y = 0


\begin{gathered} 0\text{ = -3x-1} \\ -3x\text{ = 1} \\ x\text{ = -}(1)/(3) \end{gathered}

So, we have the x-intercept as (-1/3,0)

Now, if we join the two points, we have successfully graphed the line
