Question

The coordinates of two points of a line are (3, 1) and (5, 2).
Read the following statements.
(i) Slope of the line is 2
(ii) Slope of the line is (1)/(2)
(iii) (9, 4) is a point on this line
(iv) (4, 9) is a point on this line
Now choose the correct answer from those given below.

• A. (i) and (iii) are true
• B. (ii) and (iv) are true
• C. (ii) and (iii) are true
• D. (i) and (iv) are true

Hint:

Once you find the slope is 1/2, you can immediately eliminate options (A) and (D). Then you only need to check one of the points, (9,4) or (4,9), to decide between (B) and (C). This saves time in a multiple-choice setting.

Answer 1

The Correct Option is C
