Answer:
Linear equation: y=2x-5
Nonlinear equation: y= x^2+6
Step-by-step explanation:
One linear equation from the list is y=2x-5
One nonlinear equation from the list is y= x^2+6
y=2x-5 is a linear equation because the equation has a maximum degree of 1
while y= x^2+6 is a nonlinear equation because it has a degree of 2.
NOTE: A linear equation has a degree of 1 and forms a straight line while a nonlinear equation has the degree as 2 or more than 2 and forms a curve.
