Help please ! whoever answers correctly gets brainliest :)

1: proportional

2: non-proportional

3: non-proportional

4: non-proportional

5: proportional

6: proportional

7: non-proportional

8: proportional

9. proportional.

10. proportional.

11. non-proportional.

12. proportional.

Step-by-step explanation:

I'm unsure how the proportional ones are actually calculated depending if it requires a dot on the exact origin, but depending on what I can graphically view and assume; every graph with the line running through the origin is proportional and every graph where the line does not run through the origin is non-proportional.

See below

Step-by-step explanation:

The origin is the middle.

1. Proportional.

2. Non-proportional.

3.Non-proportional.

4.Non-proportional.

5.Proportional.

6.Proportional.

7.Non-proportional.

8.Proportional

9.

6/1=6, 12/2=6, 18/3=6, 24/4=6. Proportional.

10.

3/1=3,6/2=3,9/3=3,12/4-3. Proportional.

11.

120/10=12, 220/20=11,320/30=32/3=10.6667…, 420/40=10.5. Non-proportional.

12.

60/1=60,120/2=60,240/4=60,360/6=60. Proportional.

Hope that helps! :)

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.
