Tell whether the two lines are parallel perpendicular or neither by finding their slopes. parallel perpendicular neither b (-3, 1) a (0,-3) (1, 2) (2, 0) 3. Tell whether the two lines are parallel perpendicular or neither by finding their slopes. neither perpendicular parallel b a (-3,-1) (-3, 1) (2, 0) (3,-2) 4. Match the following graphs with an approximate slope value. Use capital letters. A. 1/4 B. 0 C. -5 D. undefined slope= slope= slope = slope= 5.
