Question 608426: I am having problems understanding Solution Sets; I need some help please.
1.Graph the solution set x+2y<=3
x+2y<=4.
My graph consists of the following points.y<=-1/2 x+2 and y<=-1/2x=3/2. My lines are very close to each other (parallel to each other)diagonally from the left upper quaadrant to the left lower and right lower quadrants. The shading is below these lines.
2. Graph the solution set y<=x-1
y>=2x
I have the following points (1,2) (0,0) (1,0)(0,-1). Lines are drawn diagonally and intersect at points (-2-1), with shading in partial of the upper right quadrant and the lower left and partial lower left.
3. Graph the following solution set. x<=y^2
y>=x
My lines are diagonal from the edge of the upper right to the lower left quadrant. The next line begins at points (0,1)and makes a curve to mid of the upper left quadrant. The shading is to the left of the mid line.
Am I correct?
Thanks for your assistance.
