Variables in algebra
Variables in algebra are letters such as x, y, v, g, or call it any letter you want that can be used to represent unknown numbers.
If the value of the variable is known, you can replace the letter with the known value.
All numbers can be graphed on a number line.
Just locate the value on the number line and put a dot.
For example, graphing x = 4 gives the following graph:
Graph x = -6 on the number line
Just locate -6 on the number line and make a draw a circle at -6
Graph x = 0
Just locate 0 on the number line and draw a circle
Now, write a statement of equality for each of the following graphs. Use x as the variable.
Answer: x = -2
Graph # 2:
Answer: x = 8
