(3). The second picture represents proportional relationship.
(4). The proportional relationship with is . Option (B) is correct.
Further explanation:
Explanation:
The points in the first picture are and
The slopes between the points can be obtained as follows,
The slopes between the points are not equal. Therefore, in the first picture x and y are not in a proportional relationship.
The points in the second picture arec and
The slopes between the points can be obtained as follows,
The slopes between the points are equal. Therefore, in the second picture x and y are in a proportional relationship.
The points in the third picture are and
The slopes between the points can be obtained as follows,
The slopes between the points are not equal. Therefore, in the third picture x and y are not in a proportional relationship.
The points in the first picture are and
The slopes between the points can be obtained as follows,
The slopes between the points are equal but the slope is negative. Therefore, in the fourth picture x and y are not in a proportional relationship.
