Question

31. Give the geometric representations of y = 5 as an equation (use graph)
i) in one variable. ii) in two variables

Answer 1

Step-by-step explanation:

In two variables, we have x and y axis.

Hence, writing equation y=3 in terms of x and y

y=3

0+y=3

or 0.x+y=3        .....(1)

Put x=0 in (1) we get

0(0)+y=3

0+y=3

y=3

So, point is (0,3)

Put x=1 in (1) we get

0(1)+y=3

0+y=3

y=3

So, point is (1,3)

Hence we can say that,in two variables,y=3 is line which is parallel to x−axis

Hope it will help you. Thank you.
