Question 44483
 The first number on the ordered pair represent the x value and the second represent the y value. Substitute the the given info in the equation 3x + 4y =12 to sove for the other value.

 3(0)+4y=12
 0+4y =12
 4y/4 = 12/4
 y=3                  
 (0,3)

 3x + 4(3/4) =12
 3x + 12/4 =12
 3x + 3 -3 =12 - 3
 3x = 9
 3x/3 =9/3
 x = 3
 (3,3/4)

 3x + 4(0)=12
 3x +0 =12
 3x/3 =12/3
 x=4
 (4,0)

 3(8/3) + 4y = 12
 24/3 + 4y =12
 8 + 4y -8 = 12-8
 4y = 4
 4y/4 =4/4
 y = 1
 (8/3,1)

 (0,3)(3,3/4) (4,0) (8/3,1)

 Hope this help
