Question 408124: What is an equation of the line that passes through the point (-2, 5) and is perpendicular to the line whose equation is y = 1/2x + 5?
1. y = 2x + 1
2. y = -2x + 1
3. y = 2x + 9
4. y = -2x - 9

You can put this solution on YOUR website! What is an equation of the line that passes through the point (-2, 5) and is perpendicular to the line whose equation is y = 1/2x + 5?
----------
Its slope m = -2, so it's choice 2 or 4.
Choice #2 passes thru the point, #4 doesn't.
--> #2 y = -2x + 1
---------------------
1. y = 2x + 1
2. y = -2x + 1
3. y = 2x + 9
4. y = -2x - 9
