what is the answer to y=x+3
what is the answer to y=x+3
That is a linear equation. It means that whatever value of x you choose,
you can obtain the corresponding value of y by adding 3 to x.
When you graph it, you will have a line that extends upward as it moves
to the right, and it will cross the y axis at (0, 3). The co-efficient of
x is 1, therefore the line rises 1 unit for each 1 unit it extends to the right.
Examples that satisfy the equation would be (10, 13), (11, 14), (12, 15), etc.
To the left of the y-axis, examples would be (-18, -15), (-13, -10), (-5, -2).
