Question

Which of the following is a linear function? (89 POINTS)HURRY PLSSSSS

Answer 1

Solution:

A linear function is a straight line formed on a coordinate plane.

To classify an equation as a linear function:

• It must not have any exponent in the equation.
• If there is a fraction, the denominator of that fraction must not multiply by x.

If any of these two occurs in an equation, the line can form a curve in a line, which is a non-linear function. A non-linear function is a curved line formed on a coordinate plane.

Option A - y = x³ + 1:

• This equation has an exponent in the variable x. Hence, this is a non-linear function.

Option B - 5x/6 = y - 4:

• This equation has no exponents in the equation. Hence, this is a linear function and also our answer.

Option C - y = 8x²

• This equation has an exponent in the term 8x². Hence, this is a non-linear function.

Option D - y = 1/5x

• The denominator of the fraction on the RHS side is multiplied by x. Hence, this is not a linear function.

Hence, Option B is correct.
