Create a equation using this graph?

Answers

The formula for a straight line is y=mx+b, where m is the slope and b is the y-intercept.

To find out the slope, we use a formula known as rise/run.

Rise means how high a point goes between any two points and run is how far the space is between any two points.

We can see that there are two points give to us. Now we ask our self how high do we have to go to reach the second points’ height. If we count it we go five UP. Meaning that the rise is positive 5.
Now we see how far the two points are. If we count it, we go 1 space the LEFT meaning -1 since going left on a graph means x is getting smaller.

Now that we have he two values, we put them into rise/run

5/-1=-5

So our value of m is -5
Meaning y=-5x+b

We still have our value of b to find and we can do this by choosing any one point on the graph and substituting it into the equation. We know that one of our points is (3,0)

We put these into the equation

y=-5x+b
0=-15+b
b=15

Therefore, y=-5x+15

I am working percentages increases and decreases with problems like From 24 pencils to 30 pencils (increase question) or From 20 miles to 11 miles ( decrease question) How can I check my answers of percentages to make sure they work? Please help!

Answers

24 pencils = 100%
30 pencils = ___%
30 - 24 = 6, so:

24 / 6 = 4 (it means that there are 4 sixes in 100%)
100% / 4 = 25%

Check: 25% * 24 = 25/100 * 24 = 1/4 * 24 = 6
30 - 6 = 24 (correct)
Answer: There was an increase by 25%

20 miles = 100%
11 miles = ___%
1 mile = 100% / 20 = 5%, so:

5 * 11 = 55 [percent]
100% - 55% = 45%

Check: 45% * 20 = 45/100 * 20 = 45/10 * 2 = 9/2 * 2 = 9
20 - 9 = 11 (correct)
Abswer: There was a decrease by 45%

How do you find percentages?

Answers

To calculate percentage increase, use the following method:

First, Work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number

Now, divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.

Also, If your answer is a negative number it is a percentage decrease.

To calculate percentage decrease, use this method:

First, Work out the difference (decrease) between the two numbers you are comparing.

Decrease = Original Number - New Number

Then, divide the decrease by the original number and multiply the answer by 100.

% Decrease = Decrease ÷ Original Number × 100

Also, If your answer is a negative number then it is a percentage increase.

If you wish to calculate the percentage increase or decrease of several numbers then I recommend using the first formula. Positive values indicate a percentage increase whereas negative values indicate percentage decrease.

What is the equation of the line that has a slope of 2/3 and a y-intercept of 3?

Answers

Answer: y=2/3x+3

*Remember the original equation in slope-intercept form*

y=mx+b

*label that with what each letter stands for*

m=slope/rate of change
x=variable
b=y-intercept

*Substitute this information into the equation

y=2/3x+3
