Afarmer builds a fence to enclose a rectangular pasture. he uses 155 feet of fence. find the total area of the pasture if it is 45.5 feet long

To build a fence is perimeter so 45.5 x 2= 91
155 - 91= 64
Since that is still two sides you divide 64 by 2 and get 32.
Then area is l x w so 32 x 45.5= 1456

There is a positive association because the number of popsicles sold increases as the temperature increases.

The line of best fit would start at (0,2) and go straight thru to (100,22)

the slope being :
(0,2)(10,4) = (4 - 2) / (10 - 0) = 2/10 which reduces to 1/5.

The y int, where the line crosses the y axis, is (0,2)
