Which of the following graphs show a proportional relationship?

The graph of proportional relationship is the straight line in Quadrant I and start in the origin.

Look at the picture.

Step-by-step explanation:

The third chart, the one which shows a line.

The third chart is showing a linear function, which is bases on a proportional relationship between two variables, their ratio (which is the slope of the line) can be positive or negative, when it's positive, it means that the ratio of change is increasing, if it's negative, their ratio of change is decreasing. In other words, when this ratio is negative, the function decreases and the line is inclined to the left, when the ratio is positive, the function increases and the line is inclined to the right.

The most basic proportion function, or linear function is , the one shown in the third graph, it's translated two units upwards, that's the difference.

Therefore, the linear graph is shown a proportional linear relation between the independent variable (x), and the dependent variable (y).

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
