Question 50674
Please help: 
I need to write the equation of the line with slope -2 and y-intercept (0,0,) then I am expected to graoh the line. 
How do I do this?

DO YOU MEAN Y INTERCEPT=0?
THEN STD EQN.IS 
Y=MX+C.....WHERE M=SLOPE=-2...C=Y INTERCEPT=0
Y=-2X
GIVE VALUES TO X AND FIND Y
X...........0............1..................2..............3 ETC
Y=-2X.......0............-2.................-4.............-6..ETC.
