Answer:

\sf slope =\dfrac{-3}{2}

Step-by-step explanation:

To find the slope, mark any two point on the line.

  (-2, 4)  ; (2 , -2)

\sf x_1 = -2 ; \  y_1 = 4 \\\\x_2 = 2 ; \ y_2 = -2 \\\\ \boxed{\bf Slope = \dfrac{y_2-y_1}{x_2-x_1}}

           \sf = \dfrac{-2-4}{2-[-2]}\\\\=\dfrac{-6}{2+2}\\\\=\dfrac{-6}{4}\\\\=\dfrac{-3}{2}

Answer:

Slope is equal to -3/2.

Step-by-step explanation:

Finds two points on an exact point. For the case of demonstration, I'll use (2, -2) and (0, 1).

Now, you can either use a formula, or do the rise-over-run method. For the formula, it would be (y2 - y1) / (x2 - x1) = slope.

For this example, the equation would be (1 - (-2) / (0 - 2). Cancel out the negatives in the numerator, and you'd get (3) / (-2). This is equivalent to -3/2.

For the rise over run method, you count how many units it goes down and over. Using the same points, to get from one to the other, you need to go down three units and to the right to. Since we're decreasing, the three is negative. The "rise," or whatever increase/decrease it is, will go in the numerator, while the "run" will go in the denominator.

This would also get you -3/2. Ask your teacher whether or not they're fine with the rise-over-run method, because a few teachers require algebraic use.

The number of assists per match for the setter on your school's volleyball team has a mean of 58 and a standard deviation of 7.
serious [3.7K]
To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143
