Question 112143: which of the ordered pairs (-3,3) (9,0) (-3,-3)(-23,8)are solutions for the equations x+4y=9?
which graph would represent 3x+2y=6

divide write the results in simplest form 9/10 divided 12/5 =
divude write tge results in simplest form 31/5 divided 2 2/3 =
add 4 1/3+5 1/3 =

which of the ordered pairs (-3,3) (9,0) (-3,-3)(-23,8)are solutions for the equations x+4y=9?
You would need to try each of the ordered pairs and see which fit the equation;
(-3)+4(3)=9
-3+12=9 -- this works
(9)+4(0)=9
9=9 -- yes
(-3)+4(-3)=9
-3+(-12)=9 -- no
(-23)+4(8)=9-23+32=9 -- yes
which graph would represent 3x+2y=6
put this in slope-intercept frm;
2y=-3x+6
y=%28-3%2F2%29x%2B3
Now graph;
graph+%28400%2C400%2C+-5%2C5%2C-5%2C5%2C+%28-3%2F2%29x%2B3%29
divide write the results in simplest form 9/10 divided 12/5 =
%289%2F10%29%2F%2812%2F5%29
%289%2F10%29%2A%285%2F12%29=45%2F120=9%2F24=3%2F8
divude write tge results in simplest form 31/5 divided 2 2/3 =
%2831%2F5%29%2F2%282%2F3%29
%2831%2F5%29%2F%288%2F3%29
%2831%2F5%29%2A%283%2F8%29=93%2F24=2%283%2F45%29=2%281%2F15%29
add 4 1/3+5 1/3 =9 2/3
