Math Problem Statement
Check the descriptions that apply for the given equations to determine if they are linear or non-linear.
Solution
This question asks you to classify equations as linear or non-linear. Let’s analyze each equation in detail to determine its category:
-
:
- This is a linear equation because it can be written in the form , where (the slope) is and (the y-intercept) is .
-
:
- This is a non-linear equation because the variables and are multiplied together, creating a product term. Linear equations only have terms where variables are added, subtracted, or scaled by constants.
-
:
- This is a non-linear equation because it contains a variable in the denominator (), which introduces a reciprocal relationship.
-
:
- This is a non-linear equation because the variable is squared (), which creates a quadratic term.
-
:
- This is a linear equation because it is in the form , where and .
-
:
- This is a non-linear equation because it contains a variable in the denominator ().
Final Classification:
-
Linear:
-
Non-linear:
