Answer 1

You have a point as your given materials (x coordinate, y coordinate). 

plug in each x coordinate value into your variable x and y coordinate value into your variable y and if your equation turns out to be true meaning if something like for ex, 7=7 shows up, it's a solution whereas false statements such as 6=7 is going to indicate that that point is not a solution
