through:(4,-3), perp. to y=-2

Question

write the standard form of the equation of the line described.

through: (4,-3), perp. to y=-2

Answer 1

Hello, Cynthia

This is a good question. A little different.

First of all, remember that y=-2 is a horizontal line that passes through point (0,-2) on the y axis.  So, what we are looking for is a vertical line.  All vertical lines are written as x= a, ( where a is the value of the x coordinate that this line passes through). The problem states that this line passes thru (4,-3).  So, the equation of this line is simple x=4. 

 

I hope this helps out and thanks for posting; it keeps me busy when I am bored.
