What is the equation in point slope form of the line that passes through the points (7,5) and (-4, -1)

vlada-n [284]3 years ago

Answer:

The point slope form is: (y - 5) = 6/11(x - 7)

Step-by-step explanation:

Giving points are: (7, 5) and (-4, -1)

Find the slope m:

m = (y - y1)/(x - x1)

m = (5 - (-1))/(7 - (-4))

m = 5 + 1/7+ 4

m = 6 / 11 = 6/11

Use the point slope form with point (7, 5) and solve for y:

(y - y1) = (x - x1)

(y - 5) = 6/11(x - 7) - this is the point slope form

y - 5 = 6/11x - 42/11  

y = 6/11x - 42/11 + 5

y = 6/11x - 42/11 + 55/11

y = 6/11x + 13/11 - This is the y intercept form

Proof, use (7, 5):

f(x) = 6/11x + 13/11

f(7) = 6/11(7) + 13/11

= 42/11 + 13/11

= 55/11 = 5, giving (7, 5)

Now, you will consider Option 1, setting a maximum shower time of 10 minutes.
matrenka [14]

The maximum shower time is an illustration of mean and median, and the conclusion is to disagree with Blake's claim

<h3>How to interpret the shower time?</h3>

The question is incomplete, as the dataset (and the data elements) are not given.

So, I will answer this question using the following (assumed) dataset:

Shower time (in minutes): 6, 7, 7, 8, 8, 9, 9, 9, 12, 12, 12, 13, 15,

Calculate the mean:

Mean = Sum/Count

So, we have:

Mean = (6+ 7+ 7+ 8+ 8+ 9+ 9+ 9+ 12+ 12+ 12+ 13+ 15)/13

Mean = 9.8

The median is the middle element.

So, we have:

Median = 9

From the question, we have the following assumptions:

  • The shower time of students whose shower times are above 10 minutes, is 10 minutes
  • Other shower time remains unchanged.

So, the dataset becomes: 6, 7, 7, 8, 8, 9, 9, 9, 10, 10, 10, 10, 10

The mean is:

Mean = (6+ 7+ 7+ 8+ 8+ 9+ 9+ 9+ 10+ 10+ 10+ 10+ 10)/13

Mean = 8.7

The median is the middle element.

So, we have:

Median = 9

From the above computation, we have the following table:

               Initial    Final

Mean         9.8        8.7

Median       9         9

Notice that the mean value changed, but it did not go below 8 as claimed by Blake; while the median remains unchanged.

Hence, the conclusion is to disagree with Blake's claim

you and 3 friends go to lunch and ordered nachosthat cost 10.30. each person also orders a soda at 1.50. write an equation to sh
kicyunya [14]

Answer:

y = 4(10.30+1.50)

Step-by-step explanation:

Since there are 4 people, you and 3 others, you would multiply everything by 4. Inside the parenthesis, would be the nachos and a drink that everyone got. Since all four people got the same thing, it would be 4x10.30 + 4x1.50, which together would be y = 4(10.30+1.50)

A student ate 3/20 of all candies and another 1.2 lb. Another student ate 35 of the candies and the remaining 0.3 lb. Altogether
Ipatiy [6.2K]
The correct question is
<span>A student ate 3/20 of all candies and another 1.2 lb. Another student ate 3/5 of the candies and the remaining 0.3 lb. Altogether, what weight of candies did they eat?</span>

let
x-------> total <span>weight of candies
we know that

x=(3/20)*x+1.2+(3/5)*x+0.3
</span>x=(3/20)*x+(3/5)*x+1.5----> multiply by 20----> 20x=3x+12x+30
20x=15x+30
20x-15x=30
5x=30
x=6 lb

the answer is
6 lb
