ANSWER

No real roots.

The roots are complex or imaginary.

EXPLANATION

The quadratic equation

a {x}^{2}  + bx + c = 0

has discriminant,

D =  {b}^{2}  - 4ac

If the discriminant is less than zero , then the quadratic equation has no real roots.

The given discriminant is -9.

Since -9 is less than zero, it means the quadratic equation has complex or imaginary roots.

Which is the graph of y = _0.4x?<br><br> A.<br><br><br> B.<br><br><br> C.<br><br><br> D.
cestrela7 [59]
Y = -0.4x

1) It is a straight line
2) I passes through the origin (0,0), because the y-intercpet is 0.
3) The slope is negative, so it passes throuh II and III quadrants
4) The magnitude of the slope = 0.4
4) The angle of the line with the negative side of the x-axis is that whose tan is 0.4 => angle = 21.8 °

With all that information you can identify the graph, given that you didn't include the options.
