A. Use technology to plot the graph. Here it is using wolframalpha.com. http://www.wolframalpha.com/input/?i=y+%3D+-5;+y+%3D+3x+-+2+for+-2%3C%3Dx%3C%3D2
B. The solution is where the graphs of the lines intersect. It is at point (-1, -5).
C. y = -5 y = 3x - 2 -5 = 3x - 2 3x = -3 x = -1 The solution is (-1, -5) which is the same as with the graph.
A) you would first make the graph, and then you would put a dot on -5 on the y axis and draw the line horizontal. and then for the y=3x-2 you would put a dot on -2 on the y axis, and the use 3/1 as your slope, which means rise 3 and then go left 1 This should help you figure out B and C, hope I helped!!
