Hello!
So to find the y-coordinate we need an equation for the line. The equation we can use is
y = mx + b
In this we already know m(the slope which is 3) and we can find b by plugging in the points that are given.
10 = 3(0) + b
10 = 0 + b
10 = b
So now that we've found b, we can use this in our equation
y = 4x + b
So now we can plug in the x-coordinate that we know (2) and find the y - coordinate.
y = 4(2) + 10
y = 8 + 10
y = 18
18 is your y-coordinate
See below for the response to each question
<h3>The variable</h3>
This is the item that is being surveyed.
The surveyed item is birth weights
Hence, the variable is birth weights
<h3>The
units of the variable</h3>
From the question, we have:
Average birth weight is 6 pounds 8 ounces.
Hence, the units of the variable are pounds and ounces
<h3>The population</h3>
This is the total number of babies in Southeast Asia
Hence, the population of interest is the babies in Southeast Asia
<h3>The individual</h3>
This is the people in the survey
Hence, the individual in the study is the 100 babies that were randomly surveyed
<h3>The
parameter of interest</h3>
This is the value that gives the required information.
Hence, the parameter of interest is the average birth weight
<h3>What is the statistic involved</h3>
The statistic is the average

Answer: The Answer is 72 or 7.2x10^1
This is due to 10^2 equaling 100. 100x0.72 is 72 bec you are moving the decimal point 2 to the right.
There are 10 marks between 7 and 8, therefore each mark is equivalent to 0.1
For 8.3, count 3 marks after 8:
First convert the fraction into decimal. Then count 6 marks from 7:
Negative is infinite
positive is dependent on whether or not a can = b etc.
