Hello,
I am trying to figure out how to complete two problems from a practice placement test that I got from the internet (before I take the actual placement test at a college). I have been out of school for a long time, so please excuse me for asking for help! It is probably very simple to solve, I just can't seem to remember...
1) Which of the following equations has a graph that is a straight line?
A) y=x^2+1
B) 2x+3xy=5
C) x^2-y^2=3
D) x-y=2x
2) a line NOT parallel to y-3=ax is
A) x-3=y/a
B) x=y/a - 3/a
C) x=ay-3
D) 2ax=2y+5
E) ax-y=5a
