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

(a) (1, 2), (2, 4), (3, 6), (4, 8).

(b) (1, 1), (1, 2), (2, 1), (2, 2).

(c) (4, 2), (2, 4), (3, 3), (5, 4).

**Solution:**

(a) The graph of points (1, 2), (2, 4), (3, 6), (4, 8) is as follows:

The point A,B,C, and D leone the __straight line__.

(b)

The graph shows that the points are joined to form a Z-shape.

(c)

The above graph shows that the points are joined in a shape of T.

**✦ Try This: **Plot the given points on a graph sheet and check if the points lie on a straight line. If not, name the shape they form when joined in the given order. (a) (1, 2), (2, 4), (3, 2), (1, 2), (b) (1, 1), (1, 4), (4, 4), (4, 1), (c) (1, 1), (2, 2) (3, 3)

(a)

The given points, when joined, form a shape of a triangle.

(b)

The points which do not lie on the same straight line, when joined form the shape of the square.

(c)

As the graph reveals that all the points lie on the same straight line.
