For three points to be collinear, they must have the same slope.
Step 1. Calculate the slope of the line using the formula m = x 2 − x 1 y 2 − y 1
m = − 2 − 0 5 − 1 = − 2
Step 2. From the choices use the guess and check method.
point ( − 2 , 3 )
− 2 = − 2 + 2 5 − 3 the statement is not true
point ( 4 , 5 )
− 2 = − 2 − 4 5 − 5 the statement is not true
point ( 2 , − 3 )
− 2 = − 2 − 2 5 + 3 the statement is true
So the desired answer is ( 2 , − 3 ) .
