Multiple choice

Which of the following expressions is a linear expression?

  1. – 4x – 7xy2

  2. 4x – 3y
  3. $\frac{4}{3}$ + $\frac{1}{x} + x$

  4. x2 + 2
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The highest power of the term in the given expression is called degree. The expression having degree one is a linear expression. So, 4x – 3y is a linear expression.
