X=3-y hopefully it's the right answer
Step-by-step explanation:
Really really sorry if I'm wrong...
<u>Y2 -Y1</u>
X2 - X1
<u>-20 - - 8</u>
-9 - -5
<u>-12</u>
-4
(simplified): <u>-3</u>
-1
You would save 7 hours and 31 minutes if you take a plane
The K-constant variation is the factor of the increase-decrease relationship between the x-variable and y-variable which can be stated as y=k*x or x=y/k<span>. For example, if y variable equal 5 and the x variable equal 2 then the k-constant variation equal 2 (calculation y=k*x --> 5=2*2.5). This constant shows the relationship between the variables.</span>
