Which statements accurately describe how to determine the y-intercept and the slope from the graph below?
On a coordinate plane, a line goes through points (0, negative 6) and (3, 0).
To find the y-intercept, begin at the origin and move horizontally to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction.

Answer:
summary
Step-by-step explanation:
Answer: Choice C
To find the y-intercept, begin at the origin and move vertically to the graphed line. To find the slope, use two ordered pairs on the line and substitute into the equation m = (y2-y1)/(x2-x1)
============================================
Explanation:
The y intercept is where the graph crosses the vertical y axis. So that's why we move vertically from the origin to get to the graph.
The slope is calculated as the difference of y values over the difference in x values. We subtract in the same order for both. In other words,
slope = rise/run = (change in y)/(change in x)
Positive slope means the line goes uphill when you move from left to right. Negative slope means the line goes downhill when you move from left to right.

Roland wants to buy a jacket that is discounted 20% off the regular price. Which of the following is NOT a valid way to determine the amount of the discount?
A
Move the decimal point of the original price one place to the left and then double it.

Set up a proportion with the ratio of the original price to the amount of the discount equal to the ratio 20 to 100.
C
Multiply the original price times 0.2.
D
Divide the original price by 5.
What is the circumference of Circle O?
Answer:
[tex]14\pi[/tex]
Step-by-step explanation:
The formula for finding the circumference of a circle is 2 times pi times the radius.
Looking at the picture, we can see that the radius of the circle is 7 cm. Plugging that into the formula gives:
2*[tex]\pi[/tex]*7 = 14[tex]\pi[/tex]
Answer: 14π cm or 43.98 cm.
Step-by-step explanation: To find circumference, one must use the equation c = 2πr (c = circumference and r = radius). Plugging in the values, we get 2πr = 2*π*7 which = 14π or if you want it rounded: 43.98 cm.
represent these number as numbers in expanded form 1.45 x 10 to the 6th power.

Kimi’s dog gives birth to a litter of 4 puppies per year, on average. The relationship between time and the expected total number of puppies is shown on the graph. Which other ordered pairs would fall on this line? Select all that apply.
(0, 0)
(2, 6)
(3, 12)
(4, 14)
Answer:
(0,0) and (3,12)
Step-by-step explanation:
The ordered pairs that would fall on the line are (0, 0), (1, 4), (2, 8), (3, 12), and (4, 16).
As shown in the graph,
x-axis represents the number of years
y-axis represents the number of puppies.
The slope of the line is 4, which means that for every 1 year that passes, the number of puppies increases by 4.
The y-intercept of the line is 0, which means that if there are 0 years, then there are 0 puppies.
The ordered pairs (2, 6) and (4, 14) do not fall on the line because they do not follow the slope of the line.
For example, in the case of (2, 6), the number of puppies should be 8, not 6.
Therefore, the only ordered pairs that would fall on the line are (0, 0), (1, 4), (3, 12), and (4, 16).

An amusement park had 250 people attend during the course of 7 hours. At this rate, how many would they expect to attend over 15 hours?
Answer:
536 people
Step-by-step explanation:
What I did was I divided 250 by 7 which gives the average hour of people which is=36 people per hour
Then you multiply 35.7 by 15 which gives you=536 people at the amusement park in 15 hours.

Saba and Hena saved up Rs. 81.75 and Rs 45.25 respectively to buy a gift for
Mother’s Day. How much money in all have the sisters set aside for the gift?
Answer: $127.00

The relationship between a distance in yards and the same distance in miles is described by the equation y=1760m. Find measurements in yards and miles for distances by completing the table.
(Second question) is there a proportional relationship between a measurement in yards and a measurement in miles for in the same distance? Explain why or why not
Answer: Question 1:
Distance Measure in miles | Distance measured in yards
---------------------------------------------------------------------------------
1 | 1760
---------------------------------------------------------------------------------
5 | 8800
---------------------------------------------------------------------------------
2 | 3520
---------------------------------------------------------------------------------
10 | 17600
---------------------------------------------------------------------------------
Question 2:
Yes, there is a proportional relationship between a measurement in yards and a measurement in miles, since a change in one variable leads to a direct change in the other variable, and there exists a constant ratio between them.
