Plot the given points on a graph sheet and check if they lie on a straight line.

Question:

Plot the given points on a graph sheet and check if they lie on a straight line. If not, name the shape they form when joined in the given order.

(i)      A (0, 2),  B (0, 3.5), C (0, 5) and D (0, 6)

(ii)     P (1, 3),  Q (1, 5), R (3, 3) and S (3, 5)

(iii)    E (4, 5),  F (5, 5), G (5, 7) and H (6, 5)

(iv)    L (2, 0),  M (2, 3), N (0, 3) and O (0, 0)

(v)     J (4, 3),  K (6, 1), L (6, 5) and M (4, 7)

Solution:

(i) After joining the given points, we see that they form a straight line.


(ii) After joining the given points, we see that they form a square.


(iii) After joining the given points, we see that they form a traingle.


(iv) After joining the  given points, we see that they form a rectangle.


(v) After joining the given points, we see that they form a paralellogram.
