In a rectangular coordinate system, if a line passes through the points (-13,-18), (17,22) and (x,2) then what is the value of x? Choose the correct answer:
A) 1 B) 2 C) 3 D) 4 E) 5
The slope of the line m is rise/run = 22-(-18) / 17-(-13) = 4/3   4/3 = 22-2 / 17-x   68-4x = 66-6   x = 2   The answer is 2.
