Problem: in a rectangular coordinate system , if a line passes through the points ( - 15 , - 18 ) , ( 1522 ) and ( x , 2 ) then what is the value of x ?
Rationale: the slope of the line m is rise / run = 22 - ( - 18 ) / 15 - ( - 15 ) = 4 / 3 4 / 3 = 22 - 2 / 15 - x 60 - 4 x = 66 - 6 x = 0 the answer is c .
