Sketch the graph on your paper. Mystery image graphing worksheets are great for independent work time. Once you've taught the basics of graphing, use the hidden picture pages to reinforce the terms and skills discussed. Coordinate Graph Teaching Tips. Teachers will get a good sense of the child's learning style based on the way they complete the worksheet. Graphing Linear Inequalities EXAMPLE 1 EXAMPLE 1 Graph an Inequality (˜< or >˜) Graph 3x-y < 2. Step 1 First, solve for y in terms of x. 3x-y < 2-y < -3x + 2 y > 3x - 2 Then, graph y = 3x - 2. Because the inequality involves >, graph the boundary with a dashed line. Step 2 Select a test point in either half-plane. A simple choice is (0, 0). ,Tim and Moby risk life and limb to show you how to graph and solve inequalities. , -3 2x + 5 and 2x + 5 ≤ 7 is called a conjunction, because it uses the word and. The sentence -3 2x + 5 ≤ 7 is an abbreviation for the preceding conjunction. Compound inequalities can be solved using the addition and multiplication principles for inequalities. EXAMPLE 2 Solve -3 2x + 5 ≤ 7. Then graph the solution set. Solution We have .

Section 3.1 Solving One Step Equations A1.1.4 Solve simple equations in one variable using inverse relationships between operations such as addition and subtraction (taking the opposite), multiplication and division (multiplying by the reciprocal), raising to a power and taking a root; Using a Graphing Calculator Work with a partner. Use a graphing calculator to graph y ≥ —1 4 x − 3. a. Enter the equation y = 1— 4 x − 3 into your calculator. b. The inequality has the symbol ≥. So, the region to be shaded is above the graph of y = —1 4 x − 3, as shown. Verify this by testing a point in this region, such as (0 ... .
