Answer the following statement(s) true (T) or false (F)
1. If the x-coordinate of P is positive and the y-coordinate of P is negative, then P is in Quadrant IV. 2. If AB = ?7, BC = ?3 and AC = ?10, then A, B and C are collinear. 3. If M(a, b) is the midpoint of AB for A(c, d), then B has coordinates (2a–c, 2b–d). 4. If the slopes of two different lines are undefined, then the lines are parallel. 5. If the slope of a line is m, then the slope of any perpendicular line is -1/m.
