Equation of a line is .
A perpendicular bisector is a line that cuts a line segment connecting two points exactly in half at a 90 degree angle. To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.
Given that,
Endpoints of the line segment are () = (4, 1) and (
) = (2, -5).
First find the midpoints of the given line segment.
M =
=
M =
Now, Find the slope of the line :
It is perpendicular to the line with (4,1) and (2,-5)
Slope between () and (
) =
so,
the slope between (4,1) and (2,-5) =
= 3
perpendicular lines have slopes the multiply to get -1
3 times m=-1
m=
The equation of a line that has a slope of m and passes through the midpoints M(3,-2) is
if we want slope intercept form
If we want standard form
Hence, Equation of a line is .

Answer:
(- 7, - 4 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the turning point is
x = -
y = x² + 14x + 45 ← is in standard form
with a = 1, b = 14 , then
x = - = - 7
Substitute x = - 7 into the equation and evaluate for y
y = (- 7)² + 14(- 7) + 45 = 49 - 98 + 45 = - 4
coordinates of turning point = (- 7, - 4 )
