How do you graph an inequality
How do you graph an inequality-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 lineGraph each inequality y > x 3 62/87,21 y > x 3 Because the inequality involves >, graph the boundary using a dashed line Choose (0, 0) as a test point Since 0 is not greater than 3, shade the half±plane that does not contain (0, 0) y í8 62/87,21

2 The graph of y > 3/4x 2 is a dashed line 4 One solution to the inequality is (0, 0) 5 The graph intercepts the yaxis at (0, 2) Solve the following rational inequality Write the solution in interval notation Show the number line and breaking points or graph of the polynomial with the part of the graph that is the solution (x4)(x2)/(x3)(x5) ¡Ü0 Calculus really quick check The graph of f ′(x) is continuous and decreasing with an xintercept at x = 2Graph y ≥ 2 x 3 First, graph y = 2 x 3 (see Figure 3) Notice that the boundary is a solid line, because the original inequality is ≥ Now, select a point not on the boundary, say (2,1), and substitute its x and y values into y ≥ 2 x 3 This is not a true statement
Graph the inequality y > 3x First form the equation of the boundary line To get the equation of the boundary line, just change the > to = So the equation of the boundary line is y = 3x Now we find some points on this line When x = 1, y = 3(1) = 3, so (1,3) is on the boundary lineGraphs, Relations, Domain, and Range The rectangular coordinate system A system with two number lines at right angles specifying points in a plane using ordered pairs (x, y) consists of two real number lines that intersect at a right angle The horizontal number line is called the xaxis The horizontal number line used as reference in a rectangular coordinate system, and the verticalSubtract x x from both sides of the inequality − 3 y > 3 − x 3 y > 3 x Divide each term by − 3 3 and simplify Tap for more steps Divide each term in − 3 y > 3 − x 3 y > 3 x by − 3 3 When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign
Graphing an inequality on a number line, is very similar to graphing a number For instance, look at the top number line x = 3 We just put a little dot where the '3' is, right?👉 Learn how to solve and graph compound linear inequalities A compound inequality is an inequality having more than 1 inequality sign To solve compound inFree graphing calculator instantly graphs your math problems

graph{y>x 10, 10, 5, 5} y>x is a graph representing all values of y that are above the graph y=x so we graph y=x like normal but use a dashed line because it is y > x not y>=x then we shade in all values greater then the line y=x or in other words all values above the line Quick tip I like to think the > symbol points up so it tells me to shade all values above the line and the

See explanation Basically this means all those values of y that are less than 3 If you wish to do a 2 dimensional representation of this (graph) you plot y=3 but you use a dotted line This signifies that the value of y may not take on the value shown In this case y!=3 You indicate which side of the line relate to the permitted values of y by shadingRefer to the explanaation Explanation Graph \displaystyle{3}{x}{2}{y}{Solution Step 1 First graph 2x y = 4 Since the line graph for 2x y = 4 does not go through the origin (0,0), check that point in the linear inequality Step 2 Step 3 Since the point (0,0) is not in the solution set, the halfplane containing (0,0) is not

Write an inequality to describe the graph The dotted line has a slope of − 1 2 \frac {1} {2} − 2 1 and and a y y y intercept of 1, so the equation of the line is y = − 1 2 x 1 y=\frac {1} {2}x1 y = − 2 1 x 1 The line is dotted, so the solution set does not include the values on on the lineTap for more steps Find the values of m m and b b using the form y = m x b y = m x b The slope of the line is the value of m m, and the yintercept is the value of b b Graph a dashed line, then shade the area below the boundary line since y y is less than 1 − x 1 x Graph x−y > 2 x y Solution Substitute the x and y values into the equation and see if a true statement is obtained Answer (2, 1 2) is a solution These ideas and techniques extend to nonlinear inequalities with two variables For example, all of the solutions to y > x2 are shaded in the graph below Figure 277
