convenience sampling is the correct answer.
A convenience sample is a type of non-probability sampling method where the sample is taken from a group of people easy to contact or to reach.
<u>For example: </u> standing at a mall or a grocery store and asking people to answer questions would be an example of a convenience sample.
This type of sampling is also known as grab sampling or availability sampling. There are no other criteria to the sampling method except that people be available and willing to participate.
In addition, this type of sampling method does not require that a simple Random sample is generated, since the only criteria is whether the participants agree to participate.
the point is (3, 3) . . . . . . y = 3
Write the point-slope equation of the line through the point you know. Then evaluate that equation for x=3 to see what the value of y is.
y = m(x -h) +k . . . . slope m through point (h, k)
y = -1/2(x -9) +0 . . . . line with slope -1/2 through point (9, 0)
For x=3, the value of y is ...
y = -1/2(3 -9) + 0 = -1/2(-6) = 3
The value of y is 3.
x = -2
