Question

Please help! I need help i keep getting them wrong

Answer 1

`y = (7)/(4)x - (5)/(4)`

Explanation:

Equation of line K:
`y = (-4)/(7)x + 1`

m₁ = -4/7

The slope of line I = -1 / m₁ = -1÷(-4/7)

=
`-1 * (-7)/(4)`

= 7/4

( -5 , -10) ; m = 7/4

y - y1 = m(x - x1)

y - [-10] =
`(7)/(4)(x -[-5])`

y + 10 =
`(7)/(4)(x +5)\\`

y + 10 =
`(7)/(4)x+5*(7)/(4)\\`

`y = (7)/(4)x + (35)/(4) - 10\\\\y = (7)/(4)x + (35)/(4) -(40)/(4)\\\\y = (7)/(4)x + (35-40)/(4)\\\\y = (7)/(4)x - (5)/(4)`
