Question

why y2-1 is not a linear equation​

Answer 1

Answer:

• No, x2 = 1 is not a linear equation, because in a linear equation, variables have power 1, i.e., the degree of the equation is 1.

Answer 2

Step-by-step explanation:

y²-1 = 0

y²-1² = 0

(y+1)(y-1) = 0

y = -1 or y = +1

Since y has two values so it not a linear equation
