Answer:
xy (less than or equal to sign) 4
B does. 0-4 if you look at it goes to 15 and if you count the tallies it’s 15. Same goes for 5-9, etc. in B.
15 red, 13 white, and 10 blue. I divided 38 by three and just sorta guessed from there if that makes any sense :P hope I helped!
With each iteration, you're swapping the two coordinates, and then change sign of the first one:
First transformation
- Start with (3,1)
- Swap coordinates: (1,3)
- Change sign of the first coordinate: (-1,3)
Second transformation
- Start with (-1,3)
- Swap coordinates: (3,-1)
- Change sign of the first coordinate: (-3,-1)
Third transformation
- Start with (-3,-1)
- Swap coordinates: (-1,-3)
- Change sign of the first coordinate: (1,-3)
Answer:
B) -3
Step-by-step explanation:
1. First you have to write the equation in slope intercept form. To do that, you must have y be alone on one side.
2. move the 3x to the right side with the 5 by subtracting 3x from both sides. Since 3x will cancel on the left, y will be left alone. 
3. Now that you're in slope intercept form, you can find the slope easily. The slope will always be the number in front of x. In this case, the number in front of x is -3. Therefore, -3 is your slope!
