If the slope of the line is undefined, it means that the line is a vertical line. Vertical lines go up and down, rather than left and right. They have the form x = a, where "a" is a constant value.
Since the line passes through the point (-1, 5), the x-coordinate of the point should be the same as the constant value "a". Therefore, the equation of the line is x = -1.
The coordinates of two points on this line can be (-1, -3) and (-1, 7).
Graph the line going through the point (-1, 5) with undefined slope. Answer with two coordinates.
