-（1/4）
Step-by-step explanation:
Answer: Choice A)
y + 3 = (2/3)(x - 5)
====================================================
Explanation:
Point slope form is
y - y1 = m(x - x1)
m = 2/3 is the given slope
(x1,y1) = (5,-3) is the point the line goes through
So we have
y - y1 = m(x - x1)
y - (-3) = (2/3)(x - 5)
y + 3 = (2/3)(x - 5)
To get the variance, start with finding the mean of your data points:
(23 + 19 + 22 + 30 + 28) / 5 = 24.4
Now take each data point and subtract the mean from it, then square that value:
23 - 24.4 = -1.4 * -1.4 = 1.96
19 - 24.4 = -5.4 * -5.4 = 29.16
22 - 24.4 = -2.4 * -2.4 = 5.76
30 - 24.4 = 5.6 * 5.6 = 31.36
28 - 24.4 = 3.6 * 3.6 = 12.96
Now get the average of those new numbers. That is your variance:
(1.96 + 29.16 + 5.76 + 31.36 + 12.96) / 5 = 16.24
The standard deviation will be the square root of the variance:
√(16.24) = 4.0299 (rounded to 4DP)
