| yeah got me on the inequality one... I forget how to do that. And its been a while on graphs but I think are = 6 I don't know how you show your work on that one but I would just graph it out. Start with the first point (-4, 3) follow the slope till the x axis hits 2... Your why axis should be at 6 at that point | ||||

| Find the value of are Find the value of are so that the line that passes through (-4, 3) and (2, r) has a slope of m= 2/3. If (x1,y1) and (x2,y2) are two points, then the slope of the straight line that connects the points equals: (y2 - y1)/(x2 - x1). 2/3 = (r - 3)/(2 - -4) = (r - 3)/6 12/3 = are - 3 R = 7 | ||||
