Answer
Equation 6 (
) is linear, while Equation 7 (
) is nonlinear.
Solution
Let’s analyze each equation to determine whether it represents a linear or nonlinear function.
6.
Analysis:
-
Standard Form: To identify if this is linear, we can rearrange it into the slope-intercept form
. -
Conclusion: This equation is linear because it fits the form
, where: -
(slope) -
(y-intercept)
-
Why It’s Linear:
- Both
and are to the first power. - The graph of this equation is a straight line.
7.
Analysis:
-
Simplification: The equation can be rewritten using rational exponents:
-
Conclusion: This equation is nonlinear because:
- The variable
is under a square root, which is equivalent to raising to the power of . - The exponent of
is not 1, which violates the definition of a linear function.
- The variable
Why It’s Nonlinear:
- The presence of the square root introduces a curvature.
- The graph of this equation is a parabola, not a straight line.
Summary:
- Equation 6 (
) is a linear function because it can be expressed in the form with both variables to the first power. - Equation 7 (
) is a nonlinear function due to the square root of , which introduces a fractional exponent and curvature to its graph.
Graphical Representation:
-
Linear Function (Equation 6):
A straight line with slope -7 and y-intercept -2. -
Nonlinear Function (Equation 7):
A parabola opening to the right due to the square root function.

Bonus Knowledge
The first equation
can be rearranged into the slope-intercept form
, which clearly shows that it’s a linear function because it has a constant rate of change and forms a straight line when graphed.
On the other hand, the equation
is a non-linear function. This is because it involves the square root of the variable
, and its graph will form a curve rather than a straight line. As
increases,
does not change at a constant rate, which is characteristic of non-linear functions.
