Which one of the following gives the distance between two points (x1,y1)(x_1, y_1) and (x2,y2)(x_2, y_2) in the coordinate plane? (a)  (x2+x1)2+(y2+y1)2 \sqrt{\,(x_2 + x_1)^2 + (y_2 + y_1)^2\,} (b) (x2−x1)2+(y2−y1)2(x_2 - x_1)^2 + (y_2 - y_1)^2 (c)  (x2−x1)2+(y2−y1)2 \sqrt{\,(x_2 - x_1)^2 + (y_2 - y_1)^2\,} (d) ∣x2−x1∣+∣y2−y1∣|x_2 - x_1| + |y_2 - y_1|
