 Question 381213: Would greatly appreciate help! I need to graph the following system of linear equations: 2x-5y_<10 3x-2y<6 Please note that the underscore denotes =, so it is "less than or equal to" the given number. Here is what I have so far: I have set each equation with an equal sign and worked out my x-intercept and y-intercept coordinates like this: LINE 1 2x-5y=10 2x-5*0=10 2x=10 10/2 x=5 sooo...x coordinates are (5,0) Now for y... 2*0-5y=10 -5y=10 10/-5 y=-2 sooo... y coordinates are (0,-2) That takes care of the line for the first equation. Now for the second line denoted by the second equation: 3x-2y=6 To get x-intercept: 3x-2*0=6 3x=6 6/3 x=2 sooo... x coordinates are (2,0) Now for y... 3*0-2y=6 -2y=6 6/-2 y=-3 sooo.. y coordinates are (0,-3) In the original system of equations, line 1 should be a solid line because it is included in the equation, and line 2 would be a dashed line because it is NOT included in the equation. When I plotted these coordinates on my graph, it differed from the answer in the textbook. The book shows an open dot at (0,0.5) with a dashed line and a solid line radiating in positive directions from the open dot-not like my answer at all! Could someone please set me straight?!
