Question 49331This question is from textbook Beginning Algebra
: Please help me graph the following inequality
3x-4y<12
Thank You in advance for your help This question is from textbook Beginning Algebra
You can put this solution on YOUR website! 3x-4y<12 [Solve for y]
3x - 3x -4y<12 - 3x
-4y<12 - 3x
-4y/-4>12/-4 - 3x/-4[Switch the sign when multiplying or dividing by a negative number]
y > -3 + 3/4x
y > 3/4x - 3 [Re-arrange the terms]
Graph the same way as you would an equality: y=mx+b, except instead of using a solid black line, use a dashed line to graph.
-3 = the y-intercept
(3/4) = the slope
Plot these points: (0, -3) (4, 0) (8, 3) (-4, -6) (2, -1.5) and (6, 1.5)
Since the line is "greater than" color or shade everything above and to the left of the dashed line.

Below is a graph of y = 3/4x-3. You graph should be dashed and shaded.
