The point slope form of a line is written as y - y1 = m(x -x1)

Where m is the slope and x1 and y1 are the points on the line.

You are told the slope is 3 and the point is (2,-1/2)

x1 is 2 and y1 is -1/2

Replace those in the equation to get:

y- (-1/2) = 3(x-2)

Simplify to get the final answer:

y + 1/2 = 3(x-2)

A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. Is the r
cluponka [151]

Answer:

  not enough information

Step-by-step explanation:

Dividing altitude by hours, we find the ratios to be 400/2 = 200 ft/h and 700/6 = 116 2/3 ft/h.

These are not the same ratio, so altitude is not proportional to time.

___

However, that's not what the question asks. It ask about rate of change. We only have enough information to determine the rate of change between hour 2 and hour 6 is 300 ft in 4 hours, or 75 ft/hour. Since we don't have any other rate of change information, we cannot determine if the rate of change is proportional to anything.

_____

<em>Comment on the question</em>

We suspect the question is simply worded poorly, and that we're supposed to determine if altitude is proportional to hours. (It is not). If that is actually the question, "rate of change" needs to be left out of the question.

4, 6, 2, 8, 4, 4, 2, 10<br> Mean:<br> Median:<br> Mode:
Troyanec [42]

Answer:

Mean: 5

Median: 4

Mode: 4

Step-by-step explanation:

Mean:

1. To find the mean given a data set, you have to add up all the data points and then divide them by the number of data points there is.

  • \frac{4+6+2+8+4+4+2+10}{8}
  • \frac{40}{8}
  • 5

Therefore, the mean is 5.

Median:

1. To find the median given a data set, we first have to arrange the data points in order.

  • 2, 2, 4, 4, 4, 6, 8, 10

2. Next, we have to find which data point is in the middle. In this case, the middle number is 4.

Therefore, the median is 4.

Mode:

1. To find the mode given a data set, you just have to find which data point is the most frequent.

  • 1 data point of  2
  • 3 data points of 4
  • 1 data point of 6
  • 1 data point of 8
  • 1 data point of 10

Because the most frequent value is 4, the mode is 4.

9.3488 rounded to the nearest tenth?
Tanya [424]

Note the place values:

9 ones place value

.  (decimal point)

3 tenths place value

4 hundredths place value

8 thousandths place value

8 ten thousandths place value

You are solving for the tenth place value. Look at the digit directly right of the tenths place value. It is the hundredths place value, which is 4.

Note that when rounding, if the number next to what you are solving for, has a value of 5 or greater, you round up. If it has a value of 4 and less, you round down. In this case, it is a 4, so round down.

9.3488 rounded to the nearest tenth is 9.3

9.3 is your answer.
