The given equation is
[tex]-16x+y=-4[/tex]To find y-intercept we make x = 0.
[tex]\begin{gathered} -16(0)+y=-4 \\ y=-4 \end{gathered}[/tex]The y-intercept is (0, -4).
To find the x-intercept we make y = 0.
[tex]\begin{gathered} -16x+0=-4 \\ x=-\frac{4}{-16}=\frac{1}{4} \end{gathered}[/tex]The x-intercept is (1/4, 0).
To graph this equation, we use the axis interceptions to draw two points, then we draw a straight line through them.
