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.
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:
  1. Equation 6 ( ) is a linear function because it can be expressed in the form with both variables to the first power.
  2. 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):
    Linear Graph
    A straight line with slope -7 and y-intercept -2.
  • Nonlinear Function (Equation 7):
    Nonlinear Graph
    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.
