The general line equation in y-intercept form is given by
[tex]y=mx+b[/tex]where m is the slope and b is the y-intercept.
In our case, the given line is
[tex]p(x)=-\frac{3}{4}x-3[/tex]By comparing both equations, we can see that
[tex]\begin{gathered} y\longrightarrow p(x) \\ m\longrightarrow-\frac{3}{4} \\ b\longrightarrow-3 \end{gathered}[/tex]Therefore, the answer is
[tex]\begin{gathered} \text{slope}=-\frac{3}{4} \\ y\text{ intercept = -3} \end{gathered}[/tex]Now, the y- intercept as an ordered pair is (0,-3)
In order to graph the line, we can give values to the variable x. At least 2 values. For instance:
that is, we have 2 points: (0,-3) and (4,-6). We can connect these points and get the line:
