Question 54639: Can someone help me on this problem?
I need to complete the ordered pairs so that each is a solution for the given equation.
3x + 4y = 12
pair 1 is (0,)
Pair 2 is (, 3/4)
Pair 3 is (,0)
Pair 4 is (8/3,)
Thanks

3x + 4y = 12 [Basic equation]
Plug-in the variable that is given. Solve for the missing variable.
.
Example:
3x + 4y = 12
pair 1 is (0,y)
3(0)+4y=12 [The x value is given; solve for the y value]
0+4y=12
4y=12
y=3
Check by plugging (x=0) and (y=3) back into the original equation:
3x + 4y = 12
3(0) + 4(3) = 12 [Simplify]
0+12=12
12=12 [checks out]
.
.
Follow the same pattern for the remaining coordinate pairs.
Pair 2 is (x, 3/4)
Pair 3 is (x,0)
Pair 4 is (8/3,y)
