Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
4x + 5y = - 45 ( subtract 4x from both sides )
5y = - 4x - 45 ( divide terms by 5 )
y = - x - 9 ← in slope- intercept form
with slope m = -
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, then
y = x + c ← is the partial equation
To find c substitute (- 4, - 11 ) into the partial equation
- 11 = - 5 + c ⇒ c = - 11 + 5 = - 6
y = x - 6 → B
