Question 1. Plot the points R(-3,-4), S(3,-l) on the same co-ordinate system. (Textbook pg. no. 93) Steps for plotting the points: i. Draw X-axis and Y-axis on the plane. Show the origin. ii. Draw a line parallel to Y-axis at a distance of 3 units in the -ve direction of X-axis. iii. Draw another line parallel to X-axis at a distance of 4 units in the -ve direction of Y-axis. iv. Intersection of these lines is the point R (-3, -4). v. The point S can be plotted in the same manner. |
