A line passes through the point (1, -2) and has a slope of -9. Find the slope of the line.
Answer:
So you stated that the line passes through point (1,-2)The line has a slope of -9 So the equation of the line is found: (-2)=-9(1) + b b= 2/9 y= -9x +2/9Answer:
-9
Step-by-step explanation:
Because you said it was -9. The answer was in the question. I think your teacher might’ve tried to trick you with this easy question

MJ solved the equation -5x - 16 = 5
His work is shown below. Identify the error and where it was made.
-5x - 16 = 5
Step 1: -5x - 16 + 16 = 5 + 16
Step 2: -5x = 21
Step 3:
-5x5=215
Step 4: x = 215
Answer:
Step-by-step explanation: He add 16 together you are not suppose to add 16 you are suppose to add 5 together so instead of 16 + 16 you do 16+ 5

Ben can type 153 words in 3 minutes. At this rate, how many words can he type in 10 minutes.
Answer:
In 10 minutes, he could type 510 words
Step-by-step explanation:
153/3=51 51 words a minute 51 times 10=510
Answer:
510 words
Step-by-step explanation:
This is how I would solve this problem:
153 words = 3 minutes
153/3 = 3/3
51 words per minute
To find the number of words Ben can tye in 10 minutes, we need to multiply the unit rate (51:1) by 10. Like so:
51 words * 10 = 1 minute * 10
510 words = 10 minutes
This means that Ben can types 510 words in 10 minutes.

A storm moves at a rate of 8 miles per hour. It is 200 miles away from Freeport and headed directly for this town. The equation y = 200 – 8x represents this function. What does the slope and y-intercept represent in this scenario?
Pls see answer below.
Step-by-step explanation:
In this case, our slope is -8. This means that every hour, the storm is getting closer to the town by 8 miles per hour.
Our y-intercept is 200, which means that its' initial position is 200 miles away from the town.
Hope this helped.

After 4 hours, Samantha has 45 candies. After 6 hours, she has 35 candies.
Find the rate of change and explain what it means.
Answer:
2.922
Step-by-step explanation:
first, we have to find the unit rate to know how long it takes Samantha to make one candle. =
45 divided by 4=11.25 candles in an hour
then we will do the same for the other number.
35 divided by 6=5.8333...
the last step is to find the difference in time.
11.25-8.333-2.922
Answer:
The rate of change is 10 candies per hour.

The resoning is because I'm going to have to move the triangle.
This is Mean Median Mode Range
Calculate the data and find the mean.
21, 17, 21, 25, 23, 13
Answer: the mean is 20
Explanation: To find the mean, you add all the numbers of the data set. (21+17+21+25+23+13) = 120. Then when you have that answer, you divide it by how many numbers are in the data set (6 numbers). So then it would be 120 divided by 6 = 20.
