Answer:
y = -1/2x+4
Step-by-step explanation:
y = 2x-1
This equation is in slope intercept form y = mx+b where m is the slope
m=2
A line perpendicular will have a slope that is the negative reciprocal
m = -1/2
Using the slope intercept form
y = mx+b
y = -1/2x+b
and the point given (2,3)
3 = -1/2(2)+b
3 = -1+b
4 =b
y = -1/2x+4 is the equation of a line that is perpendicular to the original line and contains (2,3)
I think its not a correct solution of given equations.
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.
