A straight line in the xy- plane has y-intercept of 10 . On this line the x-coordinate of the point is 100 and y-coordinate is 1000 then what is the slope of the line?  Choose the correct choice: A) 2 B) 5.5 C) 6.5 D) 3.2 E) 9.9
Eq of line = Y = MX +C   C= 10   X=100   Y=100M + 10,   Substitute Y by 1000 as given in question.   1000=100M+10 , M =9.9.   correct option is 9.9
