Question

*URGENT* I need help with 5,6,7 please answer correctly and quickly

Answer 1

Explanation:

(5). (
`x_(1)` ,
`y_(1)` )

y -
`y_(1)` = m( x -
`x_(1)` )

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

( 4 , 8 )

y =
`(1)/(7)` x - 5 ; slope m =
`(1)/(7)`

Slope of line ⊥ to the given line is opposite reciprocal to
`(1)/(7)` and equal to ( - 7)

y - 8 = - 7( x - 4 )

(6).

(
`x_(1)` ,
`y_(1)` )

(
`x_(2)` ,
`y_(2)` )

m =
`( y_(2) -y_(1) )/( x_(2) -x_(1) )`

y = mx + b

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

( 4 , 3 )

( 5 , 1 )

m =
`(1-3)/(5-4)` = - 2

y - 3 = - 2( x - 4 )

y = - 2x + 11

(7). y = -
`(1)/(2)` x + 2
