Which equation represents a linear function? (1 point)

Equation 1: y = 2x2 + 1
Equation 2: y2 = 8x + 1
Equation 3: y = 5x3 − 1
Equation 4: y = 7x − 1

a
Equation 1

b
Equation 2

c
Equation 3

d
Equation 4

Answer 1

Answer:

d ) equation 4

Step-by-step explanation:

function will be linear when the highest power or degree of variable is 1.

and in above question the only linear variables are in equation 4 so d is the right answer
