First, you have to get the equation to the normal form of a line. To do this, you divide both sides by -6 to get

. The y-intercept is at -4 and your slope is 2/3. Use this to graph the equation.
The decimal moves 2 spaces to the left.
For example:
4 / 100 = 0.04
Answer: 4.2
Step-by-step explanation:
it is better for the mean deviation to be smaller because then the data in the set is not skewed and is more consistent. :)
