Question

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)

Answer 1

a the origin is the correct answer

Answer 2

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

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)
