Substituting values from the domain will give the corresponding values from the range.
Practice makes perfect
Let's graph using a table. First select some arbitrary values from the domain, then substitute them for x in the given equation. Solving for y will give us the corresponding values from the range.
x
y=x+2
Simplify
-2
y= -2+2
y= 0
0
y= 0+2
y= 2
2
y= 2+2
y= 4
Using these x and y values as ( x, y) coordinate pairs, we can plot the points. Connecting these points will give us the graph of the equation.
