Answer:

7

Step-by-step explanation:

To find the mean, add up all the values, then divide by the number of values.

1. Add the values

6 + 5 + 8 + 5 + 9 + 6 + 7 + 5 + 12 = 63

2.Divide by the number of values

9 values

63/9

Find the slope and y-intercept for this table.​
labwork [276]

Answer:

See below:

Step-by-step explanation:

To find the slope, we use the following formula:

\frac{y_{2} - y_{1} }{x_{2} - x_{1} }

For this case, we can use (6,60) as the first set of points.

We can use (4,70) as the second set of points.

Now, we can use the formula, 70-60 is for the top of the fraction (10)

We can do 4-6 to find the bottom, which is (-2)

Now, if we add the fraction back we get -> 10/-2 which is -5 for slope!

To find out the y intercept, it in simple words is "What is y when x is 0?".

We can do that by using the slope intercept formula: y=mx+b.

Once we insert our slope which is -2 we get: y=-2x+b

We can now substitute a point, lets use (6,60) so we can find out b.

We now get the equation: 60=-5(6)+b.

If we solve for that we get 90!

Once we input that, we get, y=-5x+90

Now we put in x as 0 and we get our y intercept as 90!

Write equations for the horizontal and vertical lines passing through the point (-2,-5).
erastova [34]

Answer:

  • y = -5
  • x = - 2

=============================

The horizontal line has same y- coordinate for each x- coordinate, and is parallel to the x-axis so it is:

  • y = - 5

The vertical line has same x- coordinate for each y- coordinate, and is parallel to the y-axis so it is:

  • x = - 2
