Question

Which equation represents a linear function? (5 points) Equation 1: y3 = 2x + 1 Equation 2: y = 3x + 1 Equation 3: y = 5x2 − 1 Equation 4: y = 4x4 − 1 please explain how you got the answer in depth

Answer 1

Equation 2: y=3x+1

is a linear function

The highest power of a variable of a linear function is 1

and the highest power of x and y in equation 2 is 1
