Divide both sides of the equation by $-4$: $\dfrac{-4x}{-4}=\dfrac{-100}{-4} \\x=25$ This means that the given equation is equivalent to $x=25$. Recall that the graph of an equation of the form $x=h$ is a vertical line whose x-intercept is $(h,0)$. Each point on the line has an x-coordinate of $h$. Thus, the graph of $-4x=-100$, which is the same as the graph of $x=25$, is a vertical line whose x-intercept is $(25,0)$. Each point on the line has an x-coordinate of $25$. This means that the following points are all on the line: $(25,−8), (25,8), \text{ and } (25,8)$ Plot the three points listed above then connect them using a line to complete the graph. (Refer to the attached image in the answer part above for the graph.)
