Question

A vertical line and a horizontal line intersect at the point (3,5). What are the equations of the lines?  

Answer 1

Do I use ax+by=c?

Answer 2

Y=mx+b?

Answer 3

your ordered pair has x = 3 and y = 5

so



so the so each equation is equal to the corresponding value in the point

vertical.... x = 3 horizontal, y = 5

the horizontal line has now slope... the vertical has an undefined slope
