We want to find two points that belong to the line
[tex]y+4x=-1[/tex]The easiest points to calculate are the intercepts. The x-intercept happens when y = 0, to find the corresponding x-value we just need to evaluate y = 0 on the expression for our line.
[tex]0+4x=-1\Rightarrow x=-\frac{1}{4}=-0.25[/tex]The x-intercept is (-0.25, 0).
Analogously, for the y-intercept(that happens at x = 0), we have
[tex]y+4\cdot0=-1\Rightarrow y=-1[/tex]The y-intercept is (0, -1).
Two points that belongs to this line are (-0.25, 0) and (0, -1).
The graph of this line is
