Y-8=-1/2x + (-2)
+8 +8
y=-1/2x +6
I just used a 2 step equation for it. I first used Distributive Property. Then Subtracted 8 from each side
He starts on the 1st floor. He then goes up 18 floors:
1 + 18 = 19
He took the stairwell down 3 floors
19 - 3 = 16
He then takes the elevator down 8 floors
16 - 8 = 8
He then takes the stairwell up 5 floors for his afternoon meeting
8 + 5 = 13

The mean is often the default measure of center because it includes every data point, ie its more representative. However, if you have outliers then the mean will be skewed toward the outlier. For example, with home prices, very expensive houses will make the mean larger than it should be if you focused on the main cluster of data. This is why the median home price is often measured and reported (rather than the mean home price).
Hello!
To put -3x-7y-14=0 into standard form, or ax+by=c where the a value cannot be negative, and there are no fractions or decimals, or any common factors, first add -14 to both sides to get -3x-7y=14. Then, since your a value is negative, multiply the entire equation by -1 which will result in your answer:
3x+7y=-14
Hope this helps!
