Answer:
A. Discriminant = 116
B. Number of solutions for the quadratic equation = 2
C. Type of solutions (circle one):Imaginary
D. Type of solutions (circle one):irrational
Step-by-step explanation:
The given quadratic equation is

We rewrite in standard form to get;

The discriminant is

where a=1, b=8, c=-13
We substitute to get:



Since the discriminant is great than zero, we have two distinct real roots

Answer:
y = 1/2x + 2
Step-by-step explanation:
m = -2, (3, - 1)
y - - 1 = -2(x - 3)
y + 1 = -2x +3
y = - 2x + 2
Perpendicular line slope: 1/2x
y = 1/2x +2
