Question 436191: How do you find the solution to: What is the slope of a line that is perpendicular to the graph of y= -1/2 + 4?
Answer by Alan3354(69443)   (Show Source):
You can put this solution on YOUR website! y= -1/2 + 4
y = 3.5
or y = 0x + 3.5
-------
That's a line that's "horizontal", parallel to the x-axis, slope m = 0
Perpendicular to it is the negative inverse, -1/0, "vertical", the slope is undefined.
