[tex]y=-3x-3[/tex]
To graph a linear equation:
1. Find the x-intercept
The x-intercedpt is the point when the line cross the x-axis (when y=0)
[tex]\begin{gathered} 0=-3x-3 \\ 3=-3x \\ \frac{3}{-3}=x \\ \\ x=-1 \end{gathered}[/tex]
First point (-1 ,0)
2. Find the y-intercept
The y-intercept is the point when the line cross the y-axis (when x=0)
[tex]\begin{gathered} y=-3(0)-3 \\ y=-3 \end{gathered}[/tex]
Second point (0 , -3)
3. Put in the plane the x and y-intercepts and draw a line that pass through these points:
Besides the x- and y-intercepts you can identify point (-2,3)
