Step-by-step explanation:
Change the equation to the general form [tex]Ax + By + C = 0[/tex].
[tex]y - 15 = - 6(x + 7) \\ y - 15 = - 6x - 42 \\ 6x + y - 15 + 42 = 0 \\ 6x + y + 27 = 0[/tex]
The slope
[tex] = - \frac{A}{B} [/tex]
[tex] = - \frac{6}{1} [/tex]
[tex] = - 6[/tex]
Answer: Slope is -6
Step-by-step explanation:
We want to rearrange the equation to the form of y=mx+b, where m is the slope and b the y-intercept.
y−15=−6(x+7)
y−15=−6x-42
y=−6x-42+15
y = -6x - 27
The slope is -6

What is an equation of the line that passes through the points (0, 3) and (5, -3)?
Answer:
y = -6/5x + 3
Step-by-step explanation:
You need to find the slope of the line (m) and the y-intercept of the line (b) to fill out the easiest equation of the line formula: y = mx + b. You already know b because it was given to you in one of the points! The point where x = 0 is your y intercept, which is given as (0, 3) here, so your b = 3. For m, take the difference of the y values in the points and divide them by the difference of the x values in the points. (-3-3)/(5-0) = -6/5.
Plug your values in to get y = -6/5x + 3, and you're done!

Answer:
0.064
Step-by-step explanation:
If 0.64 is ten times as much as something, then the thing you're looking for is 10 times as small as 0.64, meaning you need to divide 0.64 by 10. Doing so will give you 0.064.

The number of incidents in which police were needed for a sample of 9 schools in Allegheny County is 8, 39, 6, 12, 45, 16, 3, 0, 15. Find the first and third quartiles for the data
The first quartile is 4.5.
The third quartile is 27.5.
What are the quartiles in a data set?A quartile divides data into three points: lower, middle, and upper quartiles, resulting in four groupings of the dataset. The lower quartile, or first quartile, is designated as Q1 and is the 9 halfway number between the dataset's lowest and median values. The median is also in the second quartile, Q2. The upper or third quartile, abbreviated as Q3, is the center point of the distribution that sits between the median and the highest value.
How to solve the question?In the question, we are given the number of incidents in which police were needed for a sample of 9 schools in Allegheny County is 8, 39, 6, 12, 45, 16, 3, 0, 15.
We are asked to find the first and the third quartile for the data.
We first arrange the data in ascending order as follows:
0, 3, 6, 8, 12, 15, 16, 39, 45.
We have 9 data points.
Thus, the first quartile is the data at the point (9 + 1)/4 th observation,
or, the first quartile is the data at the point 2.5th observation,
or, the first quartile is the data at the average of 2nd and 3rd observation, = ( 3 + 6 )/2 = 4.5.
Thus, the first quartile is 4.5.
Thus, the third quartile is the data at the point 3(9 + 1)/4 th observation,
or, the third quartile is the data at the point 7.5th observation,
or, the third quartile is the data at the average of 7th and 8th observation, = ( 16 + 39 )/2 = 27.5.
Thus, the third quartile is 27.5.
