Question

State the degree of each of the following and identify it as a linear or non-linear relation.

a) y = x2 + 2x + 1

b) 3x + 3y = 6

Answer 1

Step-by-step explanation:

a. degree 2 non linear

b. degree 1 linear

Answer 2

Answer:

a) Degree 2 (Non-colinear)

b) Degree 1 (Collinear)

Step-by-step explanation:

The variable x must be either degree zero or degree 1 AND the variable y must be 1st degree in order to be a linear function.

To determine if an equation is a linear function, it must have the form y = mx + b (in which m is the slope and b is the y-intercept). A nonlinear function will not match this form.
