The answer is a pair of numbers ... one for 'x' and one for 'y' ... that makes
the statement " y = x + 8 " a true statement.
Any pair of numbers can be an answer, just as long as the 'y' number is
8 more than the 'x' number.
So there are an infinite number of answers.

x = 2, y = 84x + 8y= 4(2) + 8(8)= 8 + 64= 72
9 plus 7 equals 144. Generally, x plus y = x(x+y).
y=x+8 is a linear equation. Y is the Y point on a graph, X is the slope, and 8 is the y intercept
x = -8, y = 10
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
