R- (-3,-4)
S- (-3,-1)
T- (-1,-4)
Tough call.
You may have to use Newton's Method or something like that.
Graph y=2^x and then graph n/x on the same set of axes. You may have to assign some arbitrary value to n to make this work. From the graph you can read off the approximate coordinates of the point of intersection.
Um I think 9 5/8 is the answer to this question. I hope it is right.
135 would be y intercept
10 would be slope
Equation: y = 10x + 135
