Answer:
A
Step-by-step explanation:
is the standard deviation of x.
The standard deviation is gotten by:
1. find the average of x-values (add up all the values and divide by number of numbers, which is 5)
2. subtract the average, x bar, from each of the values, square it, and add up the difference
3. Divide that final answer by n, which is 5
4. Take the square root of the answer
<em>Now, let's find the average (x bar):</em>
<em>x bar = </em>

point slope form formula { (y-y1) = m (x-x1) }
so 1. (y-3) = 1/8 (x-3)
2. ( y- 30 ) = -4 (x-6)
3. ( y -7) = 0.25 (x +8)
4 . ( y -2 ) = 1 ( x-0)
Slope of equation :- The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.
