Question

how do i graph y=x+2

Answer 1

Create a table for x values to retireve your y values.
Example:
\[y=(1)+2 = 3\]\[y= (2)+2 = 4\]
So now we have two sets of coordinates:
(1,3) and (2,4)
Keep adding more values to x to get a better representation of the graph.

Answer 2

so do i just graph the coordinates (1,3) and (2,4)?

Answer 3

Keep going until you feel satisfied with how many points you plot.

Answer 4

Your graph would look like this:
