Answer:Equation 2: y = 5x u2212 4.5 has a graph that is a straight line.Step-by-step explanation:Given equations :

Equation 1: [tex]y = 4x^3 + 6[/tex]

Equation 2: y = 5x u2212 4.5

Equation 3: [tex]y^2 = x-1[/tex]

Equation 4: [tex]y = 2x^2 + 6[/tex].

First equation has degree 3 because power of x is 3.

Second equation has degree 1 because power of x is 1.

Third equation as power of y as 2.

And fourth equation as power of x as 2.

Note:

An equation with power of x and y or any variable only 1 to be graph be a straight line.Only second equation has power of x and y is 1.

## Therefore, Equation 2: y = 5x u2212 4.5 has a graph that is a straight line.

The equation of a straight line is in the form y = mx + c.

Among the 4 equations, it is only equation 2 that is in this form.

The equation 2: y=5x-4.5 is the correct answer.
