Given a quadratic equation
, we define the discriminant as

The number of real solutions of the equation depend on the sign of
:
- If
the equation has two solutions - If
the equation has one double solution - If
the equation has no real solutions
In this case, we have

And so this equation has no real solutions.
Answer:
The slope is 3
Step-by-step explanation:
m = rise/run
m = (y2 - y1)/(x2-x1)
points: (0,-5), (1,-2)
m = ((-5) - (-2))/ ((0) - (1))
m = (-5 + 2)/ (-1)
m = -3/-1
m = 3
