The time it takes to install 1 insulator would be 1.25 hours
Formula is y = mx + b
Answer y = - 2/3x - 3
To isolate x, we will first subtract 0.8 from both sides.
0.6x + 0.8 = 1.4
-0.8 -0.8
0.6x = 0.6
Now all we have to do is divide both sides by 0.6, because it is the number besides x.
0.6x/0.6 = 0.6/0.6
x = 1
So you get the answer of x = 1.
A plane has two dimensions and extends infinitely in both dimensions.
