Answer 1

Answer:

d)7x+5y=48

Step-by-step explanation:

AB and BC form a right angle at point B, so BC is perpendicular to AB.  

The equation of perpendicular to the line through (x₁,y₁) and  (x₂-x₁)

x+(y₂-y₁)y=(x₂-x₁)x₂+(y₂-y₁)y₂.  

Here this is (4--3)x+(4--1)y=(4--3)4+(4--1)4

that is equal to 7x+5y=48
