We know that coordinates are labeled (x,y)
The formula to find slope is (Y2-Y1)/(X2-X1)
So (2- (-7))/(-6-(-6) undefined because the denominator is zero. The line looks like a vertical line at x=-6
If 4 lbs of potatoes cost 6.78...then 1 lbs of potatoes cost 6.78/4 = 1.695...rounds to 1.70 per lb
The perimeter of the rectangle is equal to the doubled sum of the sides, and the area is equal to the product of the sides. So we have the following equation
3 x 2x = 2(3 + 2x)
6x = 6 + 4x
2x = 6
x = 3
the answer is 5.10729613...
