Aline passes through point (-2, 5) and has a slope of . points a(x, 3) and b(-2, y) lie on the line. the value of x is , and the value of y is

Since the line passes through point (-2, 5) and (-2, y), this has to be a vertical line, because the x values are identical for all vertical lines.  The y-coordinate can be any real number because the line extends from negative infinity to positive infinity.  The slope of the line is undefined (vertical lines have an undefined slope).  x = -2, because all x values are constant for vertical lines.    The equation of the line is x = -2
