If you know an equation is linear, you can graph it by finding any two solutions ( x 1, y 1) and ( x 2, y 2) , plotting these two points, and drawing the line connecting them Example 1 Graph the equation x 2 y = 7 You can find two solutions, corresponding to the x intercepts and y intercepts of the graph, by setting first x = 0 andX=y2 Graph the linear equationy = x 2 ===== Cheers, Stan HQuestion x=y2 Graph the linear equation Answer by stanbon(757) (Show Source) You can put this solution on YOUR website!
Let x = 2 then y = 2 − 2 = 0 We now have three sets of point Point P 1 → (x,y) → ( −1, − 3) Point P 2 → (x,y) → (0, −2) Point P 2 → (x,y) → (2,0) Mark these point on graph paper and draw a line through them extending it to the edges of the scales If all three dots must line upSolution 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 notMethod 1 using two points to graph a linear equation The graph of any linear equation like y = 3 x 2 or y = − x 9 is a line, and only two points are needed to define a line The idea with this method is to find two points on the line by picking values of x

The graph of a linear equation is a straight line To locate that straight line you just need two points To find a point, you give a value to one of the variables (x or y), and solve the equation to find the corresponding value for the otherSubtracting 2 x from each side gives – y ≤ –2 x Now dividing each side by –1 (and changing the direction of the inequality) gives y ≥ 2 x Graph y = 2 x to find the boundary (use a solid line, because the inequality is "≥") as shown in Figure 3 Figure 3 Graph of the boundary line for y ≥ 2x(2) 40x30y 2160 x 0 y 0 These are constraints The above is a linear programming problem The values of x and y that optimize (maximize or minimize) the value of the objective function are called the optimal solution A linear programming problem with the additional constraint that x and y are integers is called an integer programing problem
