Question

Give the geometric representations of 2x + 9 = 0 as an equation. 

(i) in one variable 

(ii) in two variables.

Answer 1

2x + 9 = 0, this equation in 

(i) One variable 2x + 9 =0 

2x = -9

(ii) 2x + 9 = 0 in two variables, 2x + 9 = 0. 

This equation passes through (-4.5, 0) and this is parallel ot y-axis. Coordinate of x = – 4.5
