A linear relationship is an equation that has a constant slope
The equation that does not represent a linear relationship is (b) y = 2x^2 + 5x
<h3>How to determine the non-linear relationship</h3>
A linear equation can take any of the following forms:
y = mx + b
y - y1 = m(x - x1)
Ax + By = c
Any form different from the above forms is not a linear equation
Using the above format as a guide, the equation that does not represent a linear relationship is (b) y = 2x^2 + 5x
