5. Select ALL of the following expressions that are linear functions (they do not need to be in slope-intercept form). y2 = 5x +2
2x + 4 = 3x - 8
y = 3x - 2
y + x2 = 12
y = x2 + 2x
1
3x + -y = 24

The following are the LINEAR functions.

Step-by-step explanation:

We know that linear functions are the equations with a straight line graph in an XY plane.

Also, a linear function is a function of the form

where m is the slope and b is the y-intercept. The only power of the variable is 1.

So, from the given expressions we can determine that:

1)

 is NOT a linear function because the power of y is 2, hence the graph won't be a straight line. Therefore, it is not a linear function

2)

This is a linear equation is an equation of a straight line, written in one variable.  The only power of the variable is 1

3)

is a linear function because it is of the form and the power of its x and y variables is 1. Hence, the function has a straight line graph.

4)

is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.

5)

is NOT a linear function because the power of x is 2, hence the graph won't be a straight line. Therefore, it is not a linear function.

6)

is a constant function and a constant function is also considered linear in this context, as it is a polynomial of degree or is the polynomial.

7)

is a linear function as the power of its x and y variables is 1. Hence, the function has a straight line graph. Therefore, it is a linear function.

In a  summary, the following are the LINEAR functions.
