Algebra 2 Graphing Linear Inequalities Practice Answer Key 19 Best
A system of linear inequalities looks like a system of linear equations, but it has inequalities instead of equations. A system of two linear inequalities is shown here. {x + 4y ≥ 10 3x − 2y < 12 { x + 4 y ≥ 10 3 x − 2 y < 12. To solve a system of linear inequalities, we will find values of the variables that are solutions to both.

Start with: y/2 + 2 > x. Subtract 2 from both sides: y/2 > x − 2. Multiply all by 2: y > 2x − 4. 2. Now plot y = 2x − 4 (as a dashed line because y> does not include equals to): 3. Shade the area above (because y is greater than ): The dashed line shows that the inequality does not include the line y = 2x−4.

Now, we will look at how the solutions of an inequality relate to its graph. Let's think about the number line in Figure 4.7.1 4.7. 1 again. The point x = 3 x = 3 separated that number line into two parts. On one side of 3 3 are all the numbers less than 3 3.

A linear inequality is an inequality that can be written in one of the following forms: Ax + By > C Ax + By ≥ C Ax + By < C Ax + By ≤ C A x + B y > C A x + B y ≥ C A x + B y < C A x + B y ≤ C Where A and B are not both zero. Recall that an inequality with one variable had many solutions.

Solve a system of linear inequalities by graphing. Step 1. Graph the first inequality. Graph the boundary line. Shade in the side of the boundary line where the inequality is true. Step 2. On the same grid, graph the second inequality. Graph the boundary line. Shade in the side of that boundary line where the inequality is true.

Exercise 2.7.19 2.7. 19. Solve the inequality t −2 ≥ 8 t − 2 ≥ 8, graph the solution on the number line, and write the solution in interval notation. Answer. Multiply both sides of the inequality by −2. Since − 2 < 0 − 2 < 0, the inequality reverses. Simplify. Graph the solution on the number line.

The equation y>5 is a linear inequality equation. y=0x + 5. So whatever we put in for x, we get x*0 which always = 0. So for whatever x we use, y always equals 5. The same thing is true for y>5. y > 0x + 5. And again, no matter what x we use, y is always greater than 5.

Step 1: We need to rewrite the inequality so that it is in slope intercept form. Step 2: Graph the line. Note that the line is solid because the inequality sign is greater than or equal to. Step 3: Shade the solution set. Since y is greater than the expression, shade the side "above" the line.
