How do you graph inequalities on a coordinate plane?

There are three steps:

  1. Rearrange the equation so “y” is on the left and everything else on the right.
  2. Plot the “y=” line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
  3. Shade above the line for a “greater than” (y> or y≥) or below the line for a “less than” (y< or y≤).

How do you find the inequality of a graph?

Plug your slope and a point into the formula y = mx + B, in which “m” is the slope, (x, y) is a point on the line and “b” is the y-intercept, to find the equation governing the inequality line. Plugging in (0, 0), you obtain 0 = 0 + b, so b = 0. Rewriting the equation, you obtain y = x/2.

How do you graph linear equations in one coordinate plane?

The x-intercept is found by finding the value of x when y = 0, (x, 0), and the y-intercept is found by finding the value of y when x = 0, (0, y). Before you can graph a linear equation in its standard form you first have to solve the equation for y. From here you can graph the equation as we did in the example above.

    How do you solve linear inequalities?

    To solve a linear inequality, you have to find all the combinations of x and y that make the inequality true. You can solve linear inequalities using algebra or by graphing. To solve a linear inequality (or any equation), you have to find all the combinations of x and y that make that equation true.

    How do you graph a coordinate plane?

    Explanation: To graph points on a coordinate plane, we must be aware that points or coordinates rather are written in the form (x,y) where x is the position on the x -axis and y is the position on the y -axis. To graph a point, we must first locate its position on the x-axis, then do the same for y-axis and find where the two points meet.
