Step-by-step explanation:
(3)
Parallel lines have equal slopes
the equation of a line in sloipe- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x + 5 ⇒ m =
y = 4x + 5 ⇒ m = 4
y = - 4x + 5 ⇒ m = - 4
y = - 4x - 9 ⇒ m = - 4
the 3rd and 4th options have equal slopes and are parallel
(4)
given a line with slope m then the slope of a line perpendicular to it is
= -
y = x + 4 ⇒ m =
y = - x + 5 ⇒ m = -
y = x + 3 ⇒ m =
y = 6x + 3 ⇒ m = 6
note that a slope of m = 6 , has a perpendicular slope of
= -
the 2nd and 4th lines are perpendicular
