to calculate the slope m , use the ' gradient formula '

m = $\frac{y_{2-y_{1} } }{x_{2-x_{1} } }$

with ( $x_{1}$ , $y_{1}$ ) = (0, - 1 ) and ( $x_{2}$ , $y_{2}$ ) = (1, 5 )

m = $\frac{5+1}{1-0}$ = 6

Answer:

d. 0.133

Step-by-step explanation:

-Standard error is calculated using the formula:

$E=\frac{\sigma}{\sqrt{n}}\\\\\sigma-=standard \ deviation\\n=sample \ size$

#We substitute the given values in the formula to solve for E:

$E=\frac{\sigma}{\sqrt{n}}\\\\=\frac{1.2}{\sqrt{81}}\\\\=0.133$

Hence, the standard error is 0.133 and the correct option is d
