    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.
