Question

give geometric representation of y=3&2x+9=0
a) in one variable and
b) in two variables ​

Answer 1

Answer:

in two variables ,we have x and y axis.

hence, writting 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

put x = 1 in 1 we get

0(1) + y = 3

y = 3

so point is (1,3)

hence, we say that in two variables , y = 3 is line which is parrallel to x

Answer 2

Answer:

y= 3

Step-by-step explanation:

2x+9=0

2x= -9

x= -9/2

x= -4.5 ans
