Determine whether the graph represents a proportional relationship. A graph is shown.


a Yes, it is a proportional relationship because the graph goes through the origin


b Yes, it is a proportional relationship because the graph is a straight line


c No, it is not a proportional relationship because the graph is not a straight line


d No, it is not a proportional relationship because the graph does not go through the origin

Answer:

y = x + 1

Step-by-step explanation:

(2,3)  (-2, -1)

line equation y - y1 = m (x - x1)

m = (-1 -3) / (-2 - 2)

= -4 / -4 = 1

y - 3 = 1 * (x - 2)

y = x -2 +3

y = x + 1

Answer:

y = 1x+1

Step-by-step explanation:

Slope-intercept form is: y=mx+b

In order to find the slope, or "m" in this formula with two given points, use the slope formula for two coordinates: m= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].  In this formula, y2 is the second coordinate's y value, y1 is the first coordinate's y-value, and likewise x2 is the second coordinate's x value, x1 is the first coordinate's x-value.

In this problem specifically, we were given coordinates (2,3) and (-2,-1).

This is how those above values would line up:

y2 = -1

x2 = -2

y1 = 3

x1 = 2

Once this is plugged into the formula it becomes [tex]\frac{-1-3}{-2-2}[/tex] , which simplifies to a slope (m) of 1.  

____________________________________________________________

Next to find the y-intercept, or "b" we simply need to plug in a coordinate's values into the slope-intercept form, and I chose (2,3) for simplicity's sake.

This would become (3) = 1(2) + b. Then just solve for b using algebra, which results in a b value of 1.  

The answer is y= 1x +1 which can alternatively be written as y=x+1

Step-by-step explanation:

Answer: 1, There is no correlation between outside temperature and number of appointments made.

Step-by-step explanation: It would be 1 because in the problem it states that even though temperatures were lower outside, their number of appointments had not changed. Because the number of appointments had not changed, there is no correlation between the temperature outside and number of appointments made.

Answer:

no correlation

Answer:

D. Henry's balloon was further from town at the beginning, but Tash's balloon traveled more quickly.

Step-by-step explanation:

With the lack of information provided, I was able to create a base and general observation and create an equation based off everything I know and believe. (may not be accurate due to lack of information and background on assignment and curriculum)

TASHA: y = 7x + 15

(current distance) = (7 miles per hour) + (starting distance)

(29) = (14) + (15)

HENDRY: y = 6x + 25

(current distance = (6 miles per hour ) + (starting distance)

(37) = (12) + (25)

Answer:

57

Step-by-step explanation:

When y=2, you just plug in the number 2 every time y appears in the equation.

Therefore, [tex]6*(2)*3-19+9*(2)*2+(24/6)...\\[/tex]

Now that can be simplified by just multiplying/dividing out each term as needed

[tex]36-19+36+4[/tex]

Now, all that is left to do is add everything together!

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

a)

The hair length is about 8 cm

b)

It takes about 18 months.

c)

it takes about 40 months.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The coordinates from the graph:

(2, 1), (3, 1.5), (4, 2), (6, 3), and (8, 4)

Where the x-axis is the number of months and the y-axis is the length of the hair in inches.

Now,

1 inch = 2.54 cm

3 inches = 3 x 2.54 = 7.62 cm
The hair length after 6 months.

= (6, 3)

= 3 inches

= 7.62 cm

Now,

6 months = 3 inches

Multiply 8/3 on both sides.

8/3 x 6 months = 8 inches

16 months = 8 inches

Now,

From the graph, we see that,

(8, 4)

This means,

In 4 months the length of the hair is 4 inches.

8 months = 4 inches

Multiply 5 on both sides.

40 months = 20 inches

Thus,

a)

The hair length is about 8 cm

b)

It takes about 18 months.

c)

it takes about 40 months.
