look it up on google :)
6z - 4 = 60
6z = 64
z = 10.66666666666666 (repeating)
Answer:
The degrees of freedom for this problem are 21
Step-by-step explanation:
Degrees of freedom:
When testing an hypothesis involving two samples, the number of degrees of freedom is given by:
In which 
is the size of the first sample and 
is the sample of the second sample.
In this question:
Samples of 9 and 14, so 
The degrees of freedom for this problem are
The degrees of freedom for this problem are 21
To graph a slope, first you should get the equation into y-intercept form (y=mx+b) m is the slope and b is the y-intercept. When graphing, a person would vertically (up or down depending whether or not b is positive or negative). Slope is diagonal in most cases. If slope is positive then the line should move up going left to right, and if it is negative the line should move downward. I always remember slope by thinking to get to the elevator then move up or down. An example would be if the equation is y=2x-1. I would start at y-intercept. In this case it would be (0,-1), then I would move right 1 and up 2 because slope is technically 2/1. The new point would be (1, 1). Keep doing the step with slope until you have enough points to draw a line through the points. I hope I was able to help you.
