The line through (6, 1) and (-3, 5) in slope intercept form

y=-4/9x+11/3

Step-by-step explanation:

Reminder: slope intercept form is y=mx+b where m= slope and b=y intercept

Two points are given; (6,1) and (-3,5)

First, find the slope

Reminder: slope is y2-y1/x2-x1

You can plug the numbers given into the equation to get 5-1/-3-6 which equals 4/-9

Now, we can use slope point form which is y-y1=m(x-x1)

Once again, plugging the numbers in (any one of the two points will work) will get

y-1=4/-9(x-6)

Simplifying it will get y=-4/9x+11/3.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
