Question 76557: 1. Complete thes ordered pairs for the equation 2y=-x-5:
(0,-5/4); (-3, -4); (-35, 15) I am not sure if I did these correctly. Help
2. Is (2, -3) a solution of 2x-3y=-5? I said no, but my classmate was yes????
3.A line parallel to the graph of 11x=9y-6 ( I don't understand)
4. Write an equaation in slope-intercept form. (don't understand)
A. Through (-4,-2) with slope -1.
B. Through (-4,6) and (-3,-1).

You can put this solution on YOUR website! 2y=-x-5, 2*-5/4=-0/2-5, -10/4=-5 wrong set of points.
---------------------------------------------------------------------
2x-3y=-5, 2*2-3*-3=-5, 4+9=-5, 13=5 Again wrong set of points
-----------------------------------------------------------------
Y=mX+b, -2=-1*-4+b, -2=4+B, B=-6, THUS THE EQUATION IS Y=-X-6
-------------------------------------------------------------
SLOPE OF THIS LINE IS (-1-6)/(-3+4)=-7/1=-7. THUS WE HAVE A SLOPE OF -7.
NOW SUBSTITUTE EITHER SET OF NUMBERS FOR X & Y AND SOLVE FOR THE Y INTERCEPT.
6=-7*-4+b
6=28+b
b=6-28
b=22 THUS THIS LINE EQUATION IS
Y=-7X+22
