A straight line in the xy- plane has slope 4 . On this line the x-coordinate of the point is 50 and y-coordinate is 300 then what is the y intercept of the plane?  Choose the correct choice from the following answers
A) 150 B) 110 C) 100 D) 200 E) 50
Eq of line = Y = MX +C   M= 4   X=50   Y=50*4 + C,   Substitute Y by 300 as given in question.   300=200+100 , 100 =100   correct option is 100
