1. (0,-3) for the third one if i'm doing it right...
(12,0) for the first
don't know about the other two

2. in the ordered pair, the first number is always the x, the second is always the y

so for the first one, y = 0
0 = 4x + 12
-12 = 4x
-3 = x

so your first one is (-3,0)

for the second:

y = 4(3/4) + 12
y = 3 + 12
y = 15, so the point is (3/4,15)

do the last one the same way, you should get (-3/4,9)

btw, the third is (0,12)

3x - 2y = 6 , 2x + 3= 6 are perpendicular lines but i need 3 ordered pairs for each. I used the m= y2-y1/x2-x1 method to establish that the slopes = -1. Any suggestions for ordered pairs for each line is much appreciated.

The ordered pairs represent values for x and y. (1,1) is x =1 and y=1. Substitute these ordered pairs in the equations and evaluate to see if are true. Then, graph the points and line to find another solution.
