You can also use the table feature on your graphing calculator to find solutions to linear equations and inequalities.

Let's say that you are asked to determine if (-3, 8) is a solution to 3*y* + *x* = 7.

**Step 1:**

Enter the equation in

Remember that first we will need to write the equation in *y* = form.

Our equation will be *y* = -
1
3
*x* + 7 or *y* = 7 −
1
3
*x*

**Step 2:**

Look at the table for this equation by pressing to access the and scroll up the table until you see an *x*-value of -3.

Our table shows that when *x* = -3, *y* = 8.

So the ordered pair (-3, 8) IS a solution to the equation.

Let's look at a linear inequality next.

Is (-1, -6) a solution for 4*x* − 2*y* > 8?

**Step 1:**

Enter the equation in

Remember that first we will need to write the equation in *y* = form.

Our equation will be:

**Step 2:**

Look at the table for this equation by pressing to access the and scroll up the table until you see an *x*-value of -1.

Our table shows that when *x* = -1, *y* = -6.
REMEMBER: we are solving an inequality. So we need to ask "Is *y* < 2*x* – 4?"

*y* < 2*x* − 4

-6 < 2(-1) − 4

-6 < -2 − 4

-6 -6

So (-1, -6) is NOT a solution to the inequality.

Use the Table feature on your calculator and determine if the given ordered pair is a solution to each linear equation or inequality.

- Is (-1, -1.5) a solution for
*y*< one-half 1 2*x*+ 3? - Is (3, 4.5) a solution for
*y*< one-half 1 2*x*+ 3? -
Is (-14, -10) a solution for 7
*y*= 4*x*− 14?
