Question

1. Draw the graph of the following:
(a) y = 3x
(b) y=x+1​

Answer 1

a)

Given equation is y=3x

When x=1,⇒y=3×1=3

When x=2,⇒y=3×2=6

When x=3,⇒y=3×3=9

x 1 2 3

y 3 6 9

Plot the points A(1,3),B(2,6),C(3,9) on the graph paper.Join these points by a straight line AC

b) y=x and y=x+1

find the nectar of graph

y=k [it is straight line passing through the origin

y=x+1

put y=0,y=1, and y=2

x=−1,x=0.and x=1

x -1 0 1

y 0 1 2

It is parallel to each other it has no solution.
