Answer: The correct option is, It is a line joining the points whose x and y coordinates add up to 4.
Step-by-step explanation:
The given equation is, 
when we take x = 1 then
when we take x = 2 then
From this we conclude that the sum of 'x' and 'y' coordinates is always equal to 4.
Hence, the correct answer is, It is a line joining the points whose x and y coordinates add up to 4.
can you please summarize more your answer because it is confusing
First One! All you have to do is count the example and see if there is a match!
2(5x + 2)2 = 48
(10x + 4)2 = 48
20x + 8 = 48
20x = 40
X = 2
Hope that helps.
Algebra is solving for the unknown so
if you have 10 apples and you give 5 to your friend, how many apples would you have so that is also 10-5=x solve for x
or it could be more complicated like (x-2)/6+4x-3=17
