In a rectangular coordinate system, if a line passes through the points (-15,-18), (15,22) and (x,2) then what is the value of x? Choose the most appropriate option.
A) -2  B) -1  C) 0  D) 1  E) 2
The slope of the line m is rise/run = 22-(-18) / 15-(-15) = 4/3   4/3 = 22-2 / 15-x   60-4x = 66-6   x = 0   The answer is 0.
