No, certainly not. The slope is undefined if and when the line in question is vertical.
The solution of
are 1 + 2i and 1 – 2i
<u>Solution:</u>
Given, equation is 
We have to find the roots of the given quadratic equation
Now, let us use the quadratic formula
--- (1)
<em><u>Let us determine the nature of roots:</u></em>
Here in
a = 1 ; b = -2 ; c = 5

Since
, the roots obtained will be complex conjugates.
Now plug in values in eqn 1, we get,

On solving we get,



we know that square root of -1 is "i" which is a complex number

Hence, the roots of the given quadratic equation are 1 + 2i and 1 – 2i
D=546m. r=1.3m/sec. 546m=1.3m/sec(t).
546m divided by 1.3m/sec = t = 420 sec (the meters will cancel out, leaving the answer to just seconds).
420 seconds divided by 60sec/min = 7 minutes.
