In a rectangular coordinate system, if a line passes through the points (-12,-18), (18,22) and (x,2) then what is the value of x?
Choose the correct answer:
A) 2
B) 3
C) 4
D) 5
E) 6
The slope of the line m is rise/run = 22-(-18) / 18-(-12) = 4/3   4/3 = 22-2 / 18-x   72-4x = 66-6   x = 3   The answer is 3.
