Question

If the three points (K,2) , ( 2,3) , & (4, +1) are collinear find the value of K __________
_​

Answer 1

Answer:

3

Step-by-step explanation:

Find a pattern:

As the y coordinate increases by 2, the x coordinate decreases by 2.

You can simplify this by saying as y increases by 1, x decreases by 2 and vice versa.

From the coordinate (4,1) to the coordinate (K,2), the y increases by 1, therefore the x decreases by 1 or 4-1=3

Therefore K=3
