Question

1
The points A and B have coordinates (-1, 3) and (5, 6) respectively. Find an equation for the line AB.​

Answer 1

Answer:

middle point of AB =(

2

7+1

,

2

−3+9

)

=(4,3)

Also slope of AB =

1−7

(9−(−3))

=−2

∴⊥ bisector of AB has slope =

−2

−1

=

2

1

∴ Equation :-

y−3=1/2(x−4)

∴2y−6=x−4

∴2y−x−2=0
