Question

I need help on number 1Find 3 point in the graph

Answer 1

$y=-3x-3$

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)

$\begin{gathered} 0=-3x-3 \\ 3=-3x \\ \frac{3}{-3}=x \\ \\ x=-1 \end{gathered}$

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)

$\begin{gathered} y=-3(0)-3 \\ y=-3 \end{gathered}$

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)
