Which graphs display a directly proportional relationship? Check all that apply. 2

The first picture, second picture,fourth picture represents proportional relationship.

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 equal. Therefore, in the first picture x and y are in a proportional relationship.

The points in the second picture are  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 slope is negative. Therefore, in the third picture x and y are not in a proportional relationship.

The points in the fourth picture are  and

The slopes between the points can be obtained as follows,

The slopes between the points are equal. Therefore, in the fourth picture x and y are in a proportional relationship.

The first picture, second picture,fourth picture represents proportional relationship.

Grade: High School

Subject: Mathematics

Chapter: Ratio and proportion

Keywords: function, First picture, second picture, proportional relationship, ratio, slope, set, set of values, set of numbers, coordinates, x-coordinate, y-coordinate.

Step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
