Question
The table shows several values of x and their corresponding values of y, where k is a nonzero constant. If the relationship between a and y is linear, which of the following defines this relationship?
- y = 2x(k+1)
- y =kx
- y=-2kx
- y=-2k-x-1
The correct answer is: y = 2x(k+1)
Slope = 2k + 2
y - intercept = 0
= y = (2k + 2) x
= 2x (k + 1)

For a sample of 13 red alder trees, an arborist measured each tree’s diameter, in centimeters (cm), at a height of 1.4 meters. The arborist then counted the number of growth rings at this height. Each point in the scatterplot represents the diameter and number of rings for each tree. A line of best fit for these data is also shown.
A red alder tree will be selected at random from the sample. What is the probability that the selected tree will have a measured diameter that is greater that is greater than 30 cm?
