Question

Slope of the lines passing through the points

I. (3,-2) and (-1,4) is - 3
II. (3,-2) and (7,-2) is 0.
III. (3,-2) and (3,4) is 1.

Answer 1

Answer:

Answer :

Slope =y2_y1

----------

x2 _x1

In case 1

Slope =4+2 6. - 3

------- = ----- = ------

- 1-3 - 4 2

In case 2

Slope =-2+2 0

--------- = ---- = 0

7-3 4

In case 3

Slope = 4+2. 6

-------- = ---- = not defined

3-3 0

So, case II is true
