1 answer:
The slope of this line is found by
.. m = (change in y)/(change in x)
.. = (7 -3)/(-4 -(-4))
.. = 4/0
.. = undefined
Any line parallel to this line will also have "undefined" slope. (It will be a vertical line, x = constant.)

Just add the 28x to each side.
Answer:
x = 7
Step-by-step explanation:
since we know y = 4, we can plug this into the equation to find x
8x - 2y = 48
8x - 2(4) = 48
8x - 8 = 48
8x = 56
x = 7
Now subtract, then add.
4 - 2 = 2 then add 12.
2 + 12 = 14.
Answer is 14.
