Which of the following points is collinear with (2, 1) and (3, 3)? a.) (0,0) b.) (1,-1) c.) (4, 4) d.) (-1, -2)

O (1,-1) is collinear with (2, 1) and (3, 3).

Step-by-step explanation:

equation of line in point slope form is

y-y1/x-x1 = m

where m is the slope of line

slope of line is given by

m = (y2-y1)/(x2-x1)

where(x1,x2) and (y1,y2) are points on the given line

So the answer is (1,-1)

y/x=18
