AboutAzeem Hussain Expertise I can answer virtually any kind of question dealing with of Math 536 and below, my forte being in parabolic functions and analytical geometry.
I'm currently learning Linear Algebra, and cannot answer questions that deal with subject matter more advanced than that.
Experience I am neither a professor nor a teacher of this subject. I am merely a student who is gifted at mathematics and enjoys being of service to his community. I frequently tutor people in math and the results are usually great.

Question What is the equation for a line that passes thru (2,5) and is perpendicular to line y=0.5x-3? The answer choices are y=-2x+9, y=2x-9, and y=-0.2x+2. I have graphed all of these and none of them appear to be perpendicular to me. What am I doing wrong? How can I solve this? Thank you for your help.
Answer Hey Marie!
Begin by finding the slope of the line. Perpendicular lines have slopes that are negative reciprocals of each other. Flip the fraction and throw a negative sign in front.
0.5=1/2 --> 2/1 --> -2/1 -->-2
Or formally,
-(0.5)^-1=-2
At this point, you just need to look at the slopes to in the choices to know which is the correct one. For verification, plug (2,5) into the equation y=-2x+9 to see if it works.
