Answer:
the points that will fall on a line where the constant of proportionality is k are A) (6,8) and B) (3,2).
Explanation:
A point (x,y) falls on a line where the constant of proportionality is k if y is equal to k times x. In other words, the equation for the line is y = kx.
Given this, we can determine which of the given points fall on a line where the constant of proportionality is k by evaluating whether the y-coordinate of each point is equal to k times the x-coordinate.
For example, if k = 2, then the point (6,8) falls on the line y = 2x because 8 is equal to 2 times 6. Similarly, the point (3,2) falls on the line y = 2x because 2 is equal to 2 times 3.
On the other hand, the point (6,4) does not fall on the line y = 2x because 4 is not equal to 2 times 6.
Therefore, the points that will fall on a line where the constant of proportionality is k are A) (6,8) and B) (3,2).
Note that if k is not specified, then any of the given points could potentially fall on a line where the constant of proportionality is k, depending on the value of k.
