The domain cannot be 0, because then the bottom is 0
So domain is (-∞, 0) U (0, <span>∞)
That rules out B
The range cannot be 0, so the answer is C
The second one is A</span>
Answer:
Step-by-step explanation:
The given data table is
x : 4 7 10 12 13
y : 5 7 12 14 18
We need to find the equation of the best fit line.
The general form of a best fit line is
.... (1)
where, m is slope and b is y-intercept.
Using the graphing calculator we get
Substitute m=1.383 and b=-1.526 in equation (1).
Therefore, the equation of best fit line is .
Answer is C qwertyuiopoiuytrewertyuioiuytrewerty
Let's say that the unknown value here is c. Although we are given two points on the line, it is only necessary to use one as there is only one unknown value, so let's say we choose the point (6, -12) and substitute this into the equation:
-12 = 1(6) - c
-12 - 6 = -c
-18 = -c
c = 18
Thus the equation for the line is y = 1x - 18
The distributive property
