The slope of the line containing the points (-5, 3) and (-2, 1) is -2/3 2/3 -3/2 user: the slope of a line that is perpendicular to a line whose slope is 3/8 is -8/3 3/8 8/3 user: the equation of the line through point (- 4, 0) and parallel to the y-axis is x = -4 y = -4 x y = -4 user: the equation of circle having a diameter with endpoints (-3, 1) and (5, 7) is (x - 4)² (y - 3)² = 25 (x - 1)² (y - 4)² = 25 (x - 1)² (y - 4)² = 100 user: a square has symmetry with respect to a
