y = ¹³/₁₅
(x, y) = (⁻¹/₃, ¹³/₁₅)
It is consistent and independent.
y = 3x + 4
-2x + y = 4

x = 0
y = 3x + 4
y = 3(0) + 4
y = 0 + 4
y = 4
(x, y) = (0, 4)
It is consistent and independent.
y = -x + 3
2x + 2y = 6
2x + 2y = 6
2x + 2(-x + 3) = 6
2x + 2(-x) + 2(3) = 6
2x - 2x + 6 = 6

Answer: Standard error.
Step-by-step explanation:
If the population is normally distributed , then the standard deviation of a sampling distribution of the sample mean ![[tex]\overline{x}](https://tex.z-dn.net/?f=%5Btex%5D%5Coverline%7Bx%7D)
[/tex] is known as standard error which depends on population standard deviation 
and the sample size (n).
It measure the variability in the sample statistics that happens by chance.
Thus, the standard deviation of a sampling distribution is called the <u>standard error</u>.
