So now that i know the slope is 2/3, how can i tell if anything is parallel to line AB? And then how can i tell what is perpendicular to line AB
A(-2,0). B(4,4)
Any line with an equal slope will be parallel.
Ok so the that answer is 2/3. How can i tell what is perpendicular?
I know now, its -3/2
Right, if a line has a slope that is the negative inverse of the slope of your line, then it is perpendicular to your line.
