In this problem, I'm going to graph the inequality why is greater than four X So there is a Y intercept here, we just don't have it written down and it's the plus zero meaning that I have an point right here at the origin And then I'm gonna use the slope for X And I'm gonna go ahead and go up a little bit more just so I can get a few more points here, make sure I'm super preciseIn these ordered pairs, the xcoordinate is smaller than the ycoordinate, so they are not included in the set of solutions for the inequality The ordered pair (−2, −2) is on the boundary line It is not a solution as −2 is not greater than −2 However, had the inequality been x ≥ y (read as "x is greater than or equal to y), then (−2, −2) would have been included (and the line would have beenFree graphing calculator instantly graphs your math problems
Pick a point not on the line to use as a test point The point (0,0) is a good test point if it is not on the lineStep by step guide to graphing linear inequalities First, graph the "equals" line Choose a testing point (it can be any point on both sides of the line) Put the value of (x,y) ( x, y) of that point in the inequality If that works, that part of the line is the solution If the values don't work, then the other part of the line is the) represents a region of the plane bounded by a parabola To graph a quadratic inequality, start by graphing the parabola Then fill in the region either above or below it, depending on the inequality
