Answer:

y = -
(4)/(3) x

Explanation:

1).
y_(1) =
m_(1)
x_(1) +
b_(1)


y_(2) =
m_(2)
x_(2) +
b_(2)


y_(1)
y_(2) if
m_(2) = -
(1)/(m_(1) )

2). (
x_(3) ,
y_(3) )

y -
y_(3) = m( x -
x_(3) )

~~~~~~~~~~~~~~~~~~

y =
(3)/(4) x + 7


m_(1) =
(3)/(4)


m_(2) = -
(4)/(3)

( 3, - 4 )

y - ( - 4) = -
(4)/(3) ( x - 3 )

y + 4 = -
(4)/(3) x + 4

y = -
(4)/(3) x
