• The sum of n terms of an AP is
• nth term of an AP is given by ,

(7 1/2) / (3/4) =
(15/2) / (3/4) =
15/2 * 4/3 =
30/3 =
10 <== there will be 10 three-fourth ft pieces
Point slope form is just a point and the slope written in the form y-y1 =m (x-x1).
Where x1 and y1 (should be subscripts) are (x1,y1) the point you are given.
So in this case all you must do is plug in the given values:
( y-y1 ) = m ( x-x1 )
( y-4. ) = -1 ( x-2 )
This being your answer
I hope this helps!!
Answer: Yes, No
Step-by-step explanation:
1st table is linear because the slope is always constant.
Second is not linear, but rather exponential.
