Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m of AB
m = =
Given a line with slope m then the slope of a line perpendicular to it is
= - = - = -
To find the midpoint of AB use the midpoint formula
M = [ (x₁ + x₂ ), (y₁ + y₂ ) ]
with (x₁, y₁ ) = )0, 0) and (x₂, y₂ ) = (2, 3), thus
M = [ (0 + 2), (0 + 3 )] = (1, )
Partial equation of perpendicular bisector is
y = - x + c
To find c substitute (1, ) into the partial equation
= - + c ⇒ c = + =
y = - x + → D
