How can I find slope
Answers
Answer 1
Answer:
To find the slope of a line, you first chooses 2 points with known coordinates that belongs to the line. Let those points be A(x1,y1) and B(x2,y2) with x2>x1.You then divide the subtraction of their Ys as y2-y1 by the subtractions of their Xs as x2-x1 (the point with the higher x comes first, this is why x2>x1). And let the slope be m.m= (y2-y1) / (x2-x1). If the slope is positive, the line croissant and y2>y1. If the slope is negative, the line is decroissant and y1>y2.Hope this helps! :)

a)46. Take 42 and divide it by 3. Then multiply 14 by 4.
b)2:1. There are 2 wings for every 1 beak on a bird.
c)15 minutes. multiply 50 times 60 and that's how many times it beats per minute. Then divide 45000 by that number and that's how many minutes it should take.
d) 28%. You have to add all the students together, and you get 200. Then you divide 56 by 200.

for the first one:
You take the number of plain chips and divide it by 3, then multiply by four. You do this because there is a 4 to 3 ratio of hot to plain chips.
42 / 3 = 14, 14 x 4 = 56.
Second one:
Birds (usually) have two wings for each beak. Why? I don't know, ask Darwin. There is a 2:1 (two to one) ratio of wings to beaks.
Third:
50 flaps per second, 60 seconds in a minute. 50 x 60 = 3000.
45,000 / 3000 = 15 minutes.
Fourth:
56 + 120 + 24 = 200
56 / 200 = 28% of the students ate pasta

Given:
radius = 18mm
height = 6mm
pi = 3.14
volume of a cone is computed by multiplying pi, radius raised to the 2nd power, and height, which has been divided by 3.
v = πr²h/3
v = 3.14 * (18mm)² x 6mm/3
v = 3.14 * 324mm² x 2mm
v = 2034.72 mm³
volume rounded to the nearest tenth would be 2034.70 mm³

ballroom dance. There are 9 students who prefer tap dance. Which equation can be used to
find the number of boys ( x) who participated in the survey?
A. 0.2 x + 25 = 9
B. 0.2( x + 25) = 9
C. 0.2(25 – 9) = x
D. 25 + x = 0.2 × 9
Answers
Given:
Girls = 25
Boys = ?
Number of students who prefer tap dance = 9
percentage of students who prefer tap dance = 20%
We need to divide 9 by 20% to get the total number of students who filled out a survey.
9 ÷ 20% = 45 total number of students
Girls + Boys = 45
25 + Boys = 45
boys = 45 - 25
boys = 20
The correct equation is: B. 0.2(x + 25) = 9
0.2x + 5 = 9
0.2x = 9 - 5
0.2x = 4
x = 4 / 0.2
x = 20
Girls = 25
Boys = ?

The correct equation is: B. 0.2(x + 25) = 9
0.2x + 5 = 9
0.2x = 9 - 5
0.2x = 4
x = 4 / 0.2
x = 20
B . Because it explains their was 25 girls and some boys so you add x to the 25
(X+25)0.2= 9
(X+25)0.2= 9

The formula for point slope form is:
y − y1 = m(x − x1)
where (x1,y1) is a point on the graph and m=slope
now lets solve for the slope of our points: (1,4) (3,8)
Slope=y2-y1/x2-x1=8-4/3-1=4/2=2
Now we can plug our information into the equation
y − y1 = m(x − x1)
y-4=2(x-1)
Now lets convert it to slope intercept form
y-4=2(x-1)
add 4 to both sides
y=2(x-1)+4
y=2x-2+4
y=2x+2
Now we can solve for the missing y value in (6,y) by plugging in the x value.
y=2x+2
y=2(6)+2
y=12+2
y=14
So the ordered pair would be (6,14)

23 = x% * 230
23 = x/100 * 230
23 = x/10 * 23
Multiply 10 on both sides.
230 = x * 23
23x = 230
Divide 23 on both sides.
x = 230/23
x = 10
10 percent of 230 is 23.
23 = x/100 * 230
23 = x/10 * 23
Multiply 10 on both sides.
230 = x * 23
23x = 230
Divide 23 on both sides.
x = 230/23
x = 10
10 percent of 230 is 23.
10% of 230 is 23
Divide 23 over 230 to get the decimal:
