Question

Each set of three points is collinear. Find each missing x- or y-value. Enter each answer to the nearest hundredth. (2, 3.37,), (10, 23.37), (6, y)

Answer 1

you can either try to match slopes, or construct a line from the first 2 in otder to input the last one

Answer 2

another idea is to move everything so that the first point is at 0,0 and then it may be easier to see a ratio

Answer 3

(2, 3.37,), (10, 23.37), (6, y)
-2 -3.37 -2 -3.37 -2 -3.37
------------------------------
0 , 0 8, 20 4, k

hmm, looks like its a midpoint :)

Answer 4

half of 20 is 10, so y-3.37 = 10 is a good solve
