For the equation y 8x 2 complete the ordered pairs 3 1
For the equation y = 8x + 2, complete the ordered pairs (3, ), (-1, ), ( , 10) and select the correct answer.
Solution
Y=8x+2.
for: (3,?)
Y= 8*3 + 2
Y= 24 + 2
Y= 26.
Pair1= (3,26).
for: (-1,?)
Y= 8*(-1) + 2
Y= -8 + 2
Y= -6.
Pair2= (-1,-6).
for: (?,10)
Y= 8x + 2
10= 8x + 2
10 - 2= 8X
8 = 8X
1 = X
Pair3= (1,10).
If Y=8X+2 those Y-8X=2.
For pair1 (3,26):
26 - 8*3 = 2.
26 - 24 = 2.
2=2.The pair is a point of the line.
The same applies with the pairs 2 and 3.
The three pairs are points of the line Y=8X+2
