Answer: B) Infinitely many solutions; both equations are equivalent
==============================================================
Work Shown:
x+y = 4 ... start with the first equation
x + (-x+4) = 4 ... replace y with (-x+4)
x-x+4 = 4
0x+4 = 4
0+4 = 4
4 = 4 ... this is a true statement regardless of what x you pick
So there are infinitely many solutions. Each solution (x,y) is of the form (x,-x+4). All solutions fall on the line y = -x+4 which is equivalent to x+y = 4. Note how we add x to both sides.
Or you could start with x+y = 4 and subtract x from both sides to get y = -x+4. Either way, we're dealing with the same equation which is why they both graph out the same line.
No this data set is not a function because two points have x coordinates of 4
Hope this helps

Answer:
y=2/3x-1 is 3/2
y=-2/3x-1 is x=3/2
y=-3/2x-1 is x= 2/3

Answer:
2
Step-by-step explanation:
We need to plot the points in a graph and see the general shape of the curve.
<em>Attached is the graph.</em>
<em />
This Upside Down "U" shaped curve is that of a parabola, which has the general form
Thus, we see, the function is a 2nd degree function, highest power is 2.
