Draw the linear graph and find the missing entries.

Consider the missing entries as a, b and c as follows

As given the graph is linear i.e. it would be straight line

When x = 1, y = 6 consider it as point A with co-ordinates (1, 6)

When x = 2, y = 12 consider it as point B with co-ordinates (2,12)

Plot points A and B and draw a straight line passing through it

When x = 3, y = a consider it as point C with co-ordinates (3, a)

But from graph point C has co-ordinates (3,18)

⇒ a = 18

When x = 4, y = b consider it as point D with co-ordinates (4, d)

But from graph point D has co-ordinates (4, 24)

⇒ b = 24

When x = c, y = 30 consider it as point E with co-ordinates (c, 30)

But from graph point C has co-ordinates (5,30)

⇒ c = 30
