Which equation represents a linear function? (1 point) Equation 1: y = 2x2 + 1
Equation 2: y2 = 3x + 1
Equation 3: y = 5x3 − 1
Equation 4: y = 4x − 1

A)Equation 1
B)Equation 2
C)Equation 3
D)Equation 4

Option D

Step-by-step explanation:

' y = 4x − 1'  would graph as a straight line. Therefore, it is a linear equation.

Liner equations are graphed as a straight line, while nonlinear equations are not.

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
