For this one use the slope formula, (y2-y1)/x2-x1)
Just to have them in one place, here are the ordered pairs
(-1,-2) (2,2)
You can do these in any order, here is how I did the problem:
(2--2)/2--1)
Your y intercepts are 2 and -2
The x are 2 and -1
Now reduce. Since you are subtracting a negative, it turns into a positive.
(2+2)/(2+1)
4/3
There is our slope: rise 4 run 3 or as a fraction 4/3.
Hope this helps!
It will take the centipede 36 minutes to travel 1 yard.
It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
We know that there are 36 inches in 1 yard.
The centipede is crawling at a rate of 6 inches per minute.
To find out how long it will take the centipede to travel 1 yard, we can set up a proportion:
6 inches/minute = x minutes/36 inches
where x is the number of minutes it will take the centipede to travel 1 yard.
Now,
6 inches x 36 inches = x minutes
216 inches = x minutes
Now,
216/6 = 36
Thus,
It will take the centipede36 minutes to travel 1 yard.

Answer: 35%
Step-by-step explanation: To find the percent decrease, we use the following formula.
The amount of change is the difference between the two numbers which in this case is 60 - 39 and the first number is 60.
60 - 39 is 21 so we are left with 21/60.
60 divided into 21 .35 times. However, our problem is asking for the percent which means we can move the decimal point two places to the right to get 35.
Therefore, the percent decrease is 35%.
