Describe the nature of the roots for this equation.

Answer:

Option D. two complex roots

Step-by-step explanation:

we know that

In a quadratic equation of the form $ax^{2} +bx+c=0$ the discriminant D is equal to

$D=(b^{2}-4ac)$

in this problem we have

$3x^{2} -2x+1=0$

$a=3\\b=-2\\c=1$

substitute the values

$D=(-2^{2}-4(3)(1))$

$D=(4-12)$

$D=-8$

The discriminant is negative

therefore

The quadratic equation has two complex roots

Answer:

Since the slope of the line is (31/4 - 25/4) / (5/4 - 3/4) = 3 that means that for every 1 that x increases, y increases by 3 so an example could be 1 3/4 for x and 9 1/4 for y.
