EXPLANATION
Given the ordered pairs:
x y
0 _1_
__ 0
__ 5
Plugging in x=0 into x + 5y = 15:
0 + 5y = 5
Dividing both sides by 5:
y = 1
Then, plugging in y=0 into x + 5y = 15:
x + 5*0 = 5
Multiplying numbers:
x = 5
Plugging in y=5 into x + 5y = 15:
x + 5*5 = 15
Multiplying numbers:
x + 25 = 15
Subtracting -25 to both sides:
x = 15 - 25
Subtracting numbers:
x = -10
Hence, the table is as follows:
x y
0 _1_
5 0
-10 5
