Answer:
You have to plug in each value of x in order to get the value of y, then write each as an ordered pair.
Step-by-step explanation:
3x + 4y = 12
3(-2) + 4y = 12
-6 + 4y =12
4y = 18
y = 18/4 = 9/2 ordered pair: (-2, 9/2)
3(0) +4y = 12
4y = 12
y = 3 ordered pair: (0, 3)
3(2) +4y =12
6 + 4y = 12
4y = 6
y = 3/2 ordered pair: (2, 3/2)
3(4) + 4y = 12
12 + 4y = 12
4y = 0
y = 0 ordered pair: (4,0)
