subtraction property of equality
Answer:
y=-.386x + 2.879
Explanation:
For these type of calculations, you would have to use a graphing calculator to use the <em>linear regression</em> function. What this does is, it takes the x & y values given on the chart and it gives you the best possible linear equation for the given data set.
The exact results were:
y = -0.3862928349 + 2.869158879
Answer: Option B.
Step-by-step explanation:
For this exercise it is important to remember that, by definition, a relation is a function if and only if each input value has an unique output value.
The input values are the values of the variable "x" and the output values are the values of the variable "y".
You can observe in the table shown in the picture, that the input value -2 has two different output values:

Notice that the input vale -1 has two different output values too:

Therefore, based on this, you can conclude that the information given in the table is a relation but not a function.
49.10 = 2.10m + 5
49.10 - 5 = 2.10m
44.10 = 2.10m
44.10 / 2.10 = m
21 = m.....the taxi drove 21 miles to take Ann home. <==
My best answer would be D
Hope it helped! Or correct me if I'm wrong.
