Given the function:
[tex]y=-2x-1[/tex]
We are going to do a table, finding the y and x intercepts and some values else to can graph.
X=0.
[tex]\begin{gathered} y=-2(0)-1 \\ y=-1 \end{gathered}[/tex]
y=0.
[tex]\begin{gathered} 0=-2x-1 \\ -2x=1 \\ x=\frac{1}{2} \end{gathered}[/tex]
x=1
[tex]y=-2*1-1=-3[/tex]
x=-1
[tex]y=-2*(-1)-1=2-1=1[/tex]
Replacing the values on the table.
We are going to graph the values:
The plot points are, looking at the table:
(0 , -1)
(-1/2 , 0)
(1 , -3)
(-1 , 1)
(2 , -5)
(-2 , 3)
