Question :

1.) Which of the following represents linear inequality in two variables?

Answer :

[tex] \green{\boxed{\rm{C. \: 3 \leqslant x + y}}}[/tex]

Explanation :

  • Linear inequality form when any two real numbers associated with this symbol.

  1. <
  2. >
  3. <
  4. >

Forming Into Linear Equation :

Just form the symbol "more than or equal to" to equal symbol (=).

  • 3 = x + y

Solving for x and y - intercept :

Solving for y-intercept

  • 3 = x(0)+y
  • 3=y
  • y=3

Solving for x-intercept

  • 3= x+y(0)
  • 3=x
  • x=3

Graphing :

How to Graph ?

  • If the symbol is greater than or less than use breaking line while more than or equal to use solid line.
