Which of the following equations would not be a line when graphed? explain how you can tell by just looking at the equations. y = 3x+4 y= 2/x y= -5x y= 6x^2 -7

Step-by-step explanation:

A linear function is one that has the following form:

Where m corresponds to the slope (degree of inclination of the line), and b the cut point on the y-axis.

Now we search among the options those that correspond to the linear function formula  

a.

Is a linear function where

b.

Is not a linear function equation since the variable x is in the denominator

c.

Is a linear function where

d.

Is not a linear function since the variable x is squared.
