Hello from MrBillDoesMath!
Answer: NO points of intersection. The two lines are parallel
Discussion:
Rewrite the equations so the variables and constants line up vertically
x - 2y + 8 = 0
x - 2y -6 = 0 (I added "x" to both sides of the second equation)
Subtract the bottom equation from the the top one:
(x - 2y + 8) - ( x - 2y -6) = 0 or
x - 2y + 8 - x + 2y + 6 = 0 or
(x-x) + (-2y +2y) + (8 + 6) = 0 or
0 + 0 + 14 = 0
14 = 0 !
No solution exists. (Another approach: What is the slope of each line? Hint: 1/2. Since the slopes are the same the lines are parallel and have no points of intersection)
Thank you,
MrB

1 because it is going by 3's
We can use proportional reasoning to solve some questions directly, such as which size of laundry detergent is the cheapest per load, or what the dimensions of the model car should be.
