Quandaries and Queries


My name is Amy
My level is college algebra
I am a student

My problem is: Write the equation of the line that contains the point (-4,6) and is perpendicular to the line y=5x+100.



Hi Amy,

I would first draw a diagram, even if it is only a mental diagram in my head.

The fact you need is that if two lines are perpendicular then the product of their slopes is -1. The slope of the line y = 5x + 100 is 5 and thus the slope of a perpendicular line is -1/5.

Can you complete it now?
