Question

Which of these points lie on the line described by the equation below?

y - 4 = -2( x - 6 )
A) (6, 4)
B) (-4, -6)
C) (4, 6)
D) ( -6, -4 )

Answer 1

Answer: A. (6, 4)

Equation of the line:

`y - 4 = - 2(x - 6) \\ y - 4 = - 2x + 12 \\ { \underline{y = - 2x + 16}}`

when x is 6:

`y = - 2(6) + 16 \\ y = - 12 + 16 \\ y = 4`
