Answer:
3x^10 + x^6 + 2x^2 - 4x + 8
Step-by-step explanation:
In descending order by powers of x: 3x^10 + x^6 + 2x^2 - 4x + 8
The slope is 5/2. You can find the slope by using y2-y1/x2-x1. 7-2/6-4= 5/2.
The answer of -30+10 is -20
-30+10=-20
Answer: Choice A
Proof:
Replace x with 1 and y with 2. This is because (x,y) = (1,2) so x = 1 and y = 2.
Doing both replacements and simplifying leads to...
2*x - y = 0
2*1 - 2 = 0
2 - 2 = 0
0 = 0
That confirms (x,y) = (1,2) is a point on the line.
It confirms (1,2) is a solution to the equation.
