What is the slope, y-intercept, and equation of a line given the points (-4, 0) and (1, 5)?

Alex Ar [27]

Answer:

$Slope: 1\\y-Intercept: 4\\Equation: y = x + 4$

Step-by-step explanation:

Given two points, we can find the equation of the line between them with the following:

$y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1}$

First, we can calculate m, or slope

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-0}{1-(-4)} = \frac{5}{5} = 1$

Next we can use the top equation and solve for b, the y-intercept

$y = mx + b\\y = x + b\\5 = (1) + b\\b = 4\\\\y = x + 4$

$Slope: 1\\y-Intercept: 4\\Equation: y = x + 4$

The number of boxes in an airmail shipment is it continuous or discrete?

trasher [3.6K]

Answer:

The number of boxes in an airmail shipment is discrete.

<em>Here is the trick:</em> If you can count it with your fingers, it is discrete, otherwise it is continuous.

*Assume you have a lot of fingers sometimes.

An example of something discrete would be the number of people in a room, because you cannot ever have half a person it means you will always have a whole number and thus discrete.

Something continuous would be how tall you are. You may tell everyone that you are 5'8 but really you are probably 5 foot 8.10444124(some crazy long decimal) inches. Additionalyl people are constantly growing and shrinking at all times throughout their lives due to the gravity, bad posture and natural growth thus it is variable that is varying and continous.

Aria studied the traffic trends in India. She found that the number of cars on the road increases by 10% each year. If there wer

denpristay [2]

Answer:

8,800,000cars

Step-by-step explanation:

Given the initial amount of cars = 80,000,000

If there is 10 % increase in the first year;

Increment = 10% of 80,000,000

Increment = 0.1 * 80,000,000

Increment = 8,000,000

Amount of car in year 2 = 80million + 8million = 88million

Year3;

Amount of car in year 3 = 88,000,000+(10%of88million)

Amount of car in year 3 = 88,000,000+8,800,000

Amount of car in year 3 =96,800,000

Differences in the number of cars = 96,800,000 - 88,000,000

Differences in the number of cars = 8,800,000cars

<em>Hence there are 8,800,000cars in years 3 than year 2</em>

sara fed each of her three dogs 3/4 cup of dog food for breakfast. How much dog food did Sara feed her dogs in all ?

Bess [88]

This is a multiplication problem.
3*3/4 is equal to (3*3)/4, which is equal to 9/4. This can be further simplified to the mixed number 2 1/4
