Question

give the geometric representation of 2x +9=0 as an equation (i) in one variable (ii) in two variable

Answer 1

Answer:

Step-by-step explanation:

Give the geometric representation of 2x +9=0 as an equation (i) in one variable (ii) in two variable

2x + 9 = 0

=> x = -4.5

2x + 9 = y

x           y

-5         -1

-4          1

-3           3

-2         5

-1           7

0           9

1            11

2           13

Answer 2

(1) In one variable, 2x + 9 = 0 represents a point x = -9/2 = -4.5

(2) In two variables, 2x + 9 = 0 represents a straight line passing through point (−4.5, 0) and parallel to y-axis. It is a collection of all points of the plane, having their x-coordinate as 4.5
