Check out the work in the picture.
<span>The median is a better measure of center when there is an outlier which will make the mean not be a good estimate of the center. Option B has $1075 as an outlier (i.e. it is far away from the other data sets). Hence, the median will be a better estimate of the center. Similarly, 94 is an outlier in option C and hence, the median is a better estimate. Options A and D has no outliers, making the mean a good estimate of the centre.</span>
The answer is D, y - 4 = -2(x - 1).
Point Slope Form: y - y₁ = m(x - x₁)
Info Given:
Coordinates - (1,4)
Slope: -2
(1,4)
x₁ y₁
Plug slope and point into formula: y - 4 = -2(x -1)
The answer to the first one is y=2 and x=6 and for the second one it is y=2 and x=6
