Which lines are perpendicular to the line y-1 = (x+2)? Check all that apply. y + 2 = -3(x - 4)
y-5= 3(x + 11)
y=-3x - 5
y = -x-2
3x + y = 7
Intro

y = -x - 2

Step-by-step explanation:

Simplifying the equation of our line;

y - 1 = (x + 2)

y = x + 3

The slope of our line is 1

The slope of the perpendicular line(s) must be -1 (the product of slopes of two perpendicular lines = -1)

The line whose slope is -1 (from the choices) is the one whose equation is:

y = -x - 2

ratio is 2 : 9

the answer is three

13.5 : 3
