Question

Which of the following equations is not a linear equation? a. y = x + 6 b. y2 = x2 + 3 c. x = 5 d. 2x = 3y

Answer 1

Answer:

b. y^2 = x^2 + 3   not a linear equation

Step-by-step explanation:

Linear equations are equations in which the variable is in the first degree, or only to the first power.

a. y = x + 6    Nothing above the first power

b. y^2 = x^2 + 3   X and y are to the second power

c. x = 5   Only to the first power

d. 2x = 3y  Only to the first power

Answer 2

Of the four listed equations, B is the only equation that is not linear.

A linear equation is any equation that results in a straight line, as each value is a fixed number from the previous.

In a non-linear equation, a variable is being raised to a power, which results in a curved line.
