Write the slope-intercept form of the equation of each line. Identify the slopes y-intercept

Answers

Answer:

10) m: 6

b: 5

y= 6x +5

12) m: -2

b: -1

y= -2x-1

14) m: 1

b: 0

y= x

Step-by-step explanation:

The slope-intercept form is the form y=mx+b

m is the slope. You can find it by finding two points that the line intersects, and counting the number of units between them.

Remember the slope is "rise over run", so, the difference in y over the difference in x.

b is the y-intercept. You can find it by looking at where the line crosses the y-axis.

Hope this helps you out!

Harry fills up his Jeep with gasoline and notes that the odometer reading is miles. The next time he fills up his Jeep, he pays for gallons of gasoline. He notes his odometer reading is miles. How many miles per gallon did he get?

Answers

Complete question :

Harry fills up his Jeep with gasoline and notes that the odometer reading is 23,568.7 miles. The next time he fills up his Jeep, he pays for 12.6 gallons of gasoline. He notes his odometer reading is 23,706.3 miles. How many miles per gallon did he get?

Answer:

10.9 miles per gallon

Step-by-step explanation:

Given that :

Odometer reading when filled up with gasoline = 23,568.7 miles

Odometer reading with 12.6 gallons of gasoline = 23,706.3 miles

Miles per gallon gotten :

(Current Odometer reading - reading when filled up) / gallon of gasoline

(23706.3 - 23568.7) / 12.6

= 10.920634

= 10.9 miles per gallon

write the point slope form of the line that passes through -8, 2 and is perpendicular to the line with a slope of negative 8

Answers

Answer:

y = -1/8x + 1

Step-by-step explanation:

Line perpendicular to 8 is -1/8

If the line were to start at the origin, then y- intercept would be 0, and it would pass through the point (-8, 1) To pass through point (-8, 2), add 1 to y in the first example.

Frogs: The population of a species of frog declines by 24% every year. Suppose 100 frogs are released into a pond. Which exponential model represents this population?

Answers

Answer:

p = 100(1 + 0.24)^n

Step-by-step explanation:

If this were exponential growth, we'd use the model p = 100(1 + 0.24)^n, where n is the number of years. But here we have exponential decline, which requires subtracting 0.24 in the formula instead of adding it to 1:

p = 100(1 - 0.24)^n = 100(0.76)^n

Consider the line y=5x -3 Find the equation of the line that is patellar to this line and passes through the point (-8, -3) Consider the line y=5x -3

Answers

Answer:

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: [tex]y = 5x+37[/tex]

Step-by-step explanation:

Given equation of line is:

[tex]y=5x-3[/tex]

The general form of equation of line in slope-intercept form is written as:

[tex]y = mx+b[/tex]

Here m(co-efficient of x) is the slope of the line and b is the y-intercept.

Comparing the given equation with the general form we get

m = 5

Two parallel lines have same slope so the slope of any line parallel to given line will also be 5.

Let m1 be the slope of required line parallel to y=5x-3

Then m1=5

Putting in general form

[tex]y = m_1x+b[/tex]

[tex]y=5x+b[/tex]

To find the value of b(y-intercept) the given point has to be put in the equation from which the line passes.

The point is (-8,-3)

[tex]-3 = 5(-8)+b\\-3 = -40+b\\b = -3+40\\b = 37[/tex]

Putting the value of b and m1, we get

[tex]y = 5x+37[/tex]

Hence,

The equation of the line that is parallel to given line and passes through the point (-8, -3) is: [tex]y = 5x+37[/tex]

Fires not only create more opportunity but also safety. Through fires we can guarantee the safety of catastrophic fires.Fires help improve our habitats. Fires burn and destroy unnecessary fuel, by this catastrophic fire numbers will be greatly decreased. Also, when these fires burn dead areas that have dead trees and other plants, it takes that nutrients and gives it back to the ground. After these fires our done the soil is greatly benefited with nutrition.When the soil is improved so is the number of plants. More and more endangered plants can be saved. Endangered forests can be restored with the help of fires. With controlled fires removing areas that are filled with dead plants, it gives seeds the chance to grow. With the help of this flame, we can save our forests.Many plants and animals actually rely on fires. In fact the world's largest species of trees, the giant Sequoias, require fires to reproduce. This giant also is in fact nearly fire proof so, the population of the species will not be affect negatively but will be affected in a very positive way. The arguably 8th Wonder of the World requires fire so their cones can open. When heat attacks the cones, the seeds are released and scattered on the ground. With fire we can keep the population of this Wonder up.Because of these and many other reasons, fires are in fact good. Fire is necessary for plant growth, and saves our forests. The controlled flame also provides safety for us and animals. In the end, fires should be supported and should continue to happen.
