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
x=10-y
Simplify
-2
( -2)=10-y
y= 12
0
( 0)=10-y
y= 10
2
( 2)=10-y
y= 8
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.
