A linear equation 2x+7=0, geometrically can represent a

line but not a point

point but not a line

both a line and a point

neither a line nor a point

​

Answer 1

solution:

a) in one variable,

2y+7=0

➡️2y= -7

equation (i) is an equation of one variable i.e, 'y'.

b)in two variables ,

2y+7=0

➡️ 2y=-7

➡️0x +2y = -7

equation (ii) is represented as an equation of two variables ie 'x' and 'y'
