Answer:
slope intercept form is y=mx+b
Step-by-step explanation:
y= y cordinate point
x= c cordinate point
m= slope (rise over run)
b= y intercept (where a line intercepts the y axis)
simplify the following rational expression?
Anyone know the answer to this?
Answer
The questions just asking to evaluate y = 8x + 3 for 5 values of x = 2, 4, 6, 8, and 10.
So:
y = 8x + 3
x = 2, y = 8(2) + 3 = 16 + 3 = 19, (2,19)x = 4, y = 8(4) + 3 = 32 + 3 = 35, (4,35)x = 6, y = 8(6) + 3 = 48 + 3 = 51, (6,51)x = 8, y = 8(8) + 3 = 64 + 3 = 67, (8,67)x = 10, y = 8(10) + 3 = 80 + 3 = 83, (10,83)I'd look for a chart with the above values. Make sure that the chart has ALL these values though; I assume that some of the charts, like the one on the picture you sent, have very similar answers.

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.

What is the distance between the points (2,-6)and(-3,6)
Answer:
Step-by-step explanation:
We can find the distance by using the distance formula.
d= √(x2-x1) ² + (y2-y1)²
For points (x1 = 2, y1 = -6) and ( x2 = -3, y2 = 6)
d= √(-3-2)² + (6 -(-6))², add and subtract what is inside of the parenthesis
d= √(-5)² + ( 12)², square the positive and negative number and get a positive
d= √25 + 144, add the numbers under the square root
d = √169, use the fact that 13*13= 169 to solve the square root
d= 13

Answer:
-1
Step-by-step explanation:
From the graph, the y-coordinate of the circled point on the y-axis is the value of f(0). (The y-axis has equation x=0.) That coordinate is -1, so f(0) = -1.
__
From the equation, substituting x=0 makes all of the x-terms disappear, leaving only the constant.
f(0) = -0 +0 -1
f(0) = -1

Solve the equation for y. Then find the value of y for each value of x. 2x - 7y = 19; X = - 2, 0, 2
PLEASE HELP
Answer:
y=-23/7;y=-19/7;y=-15/7
Step-by-step explanation:
when x is -2 then y is;
2(-2)-7y=19
-4-7y=19
-7y=23 divide both sides by -7
y=-23/7
when x=0 then y is;
2(0)-7y=19
-7y=19
y=-19/7
when x=2 then y is;
2(2)-7y=19
4-7y=19
-7y=15
y=-15/7
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!

Hello !
Answer:
[tex]\boxed{ \begin{gathered} \sf \star\ \ y=11x+62 \\ \sf\star\ \ Slope : 11\\\sf \star\ \ y-intercept: 62 \end{gathered}}[/tex]
Step-by-step explanation:
The line pass through the two following points :
[tex]\sf(-5,7)[/tex][tex]\sf (-6,-4)[/tex]The slope-intercept form of a line is of the form [tex]\sf y=mx+b[/tex] where m is the slope and b is the y-intercept.
We're looking for the two coefficients m and b.
Let's replace x and y with their values :
[tex]\begin{cases}\sf 7=-5m+b \\\sf -4=-6m+b\end{cases}[/tex]
We get a system of two equations to solve.
Let's subtract the second line from the first one and solve for m :[tex]\sf 7-(-4)=-5m-(-6m)+b-b\\\iff \sf 7+4=-5m+6m\\\iff \boxed{\sf m=11}[/tex]
Let's substitute 11 for m in the first equation :
[tex]\sf 7=-5\times11+b\\\iff \sf 7=-55+b\\\iff \boxed{\sf b=62}[/tex]
The slope-intercept form of the equation is [tex]\sf y=11x+62[/tex].
The slope is 11.
The y-intercept is 62.
Have a nice day ;)
