First of all you need to make sure that each side has only letters and numbers, for this equation you first need to subtract 6 of each side, this way you can change the equation appearence without changing it's value, because if you do something in both sides of an equation, it's ok. After subtracting 6 of each side you can divide both sides for -4, this way you'll take only x in the left side and 12/-4 on the other, this way you will see that x = -3

6 - 4x = 18

6 - 4x - 6 = 18 - 6

-4x = 12

-4x/-4 = 12/-4

x = -3

Suppose the line of best fit is being found for some data points that have an r-value of 0.793. If the standard deviation of the

alexandr1967 [171]

Answer: 0.393

Explanation: If the given quantities are r-value (or Pearson's coefficient) and the standard deviations of x and y coordinates, we'll use the following formula for slope:

$m = \frac{rs_y}{s_x} 

$

where:
m = slope of the best fit line
r = r-value = 0.793
$s_x$ = standard deviation of x-coordinates = <span>5.591
</span> $s_y$ = standard deviation of y-coordinates = 2.772

So, the slope is calculated as follows:

$m = \frac{rs_y}{s_x}
\\ = \frac{(0.793)(2.772)}{5.591}
\\ \boxed{m \approx 0.393}$

Hence, the slope in 3 decimal places is 0.393.
