i cant see the lines clearly, soo all i can say is that:
- x is the horizontal line, y is vertical
- quadrant I all positive
- quadrant II x negative, y positive
- quadrant III all negative
- quadrant IIII y positive, y negative
- for every line the point passes, it counts as 1
- each point does not have a certain order to go in the chart
sorry, but this is the best i can do for now! make sure your pictures are clear next time :D
We have 8/27 + 25/9 = 24/81 + 225/81 = 249/81 = 3.07;
For 4 4 to 5 16 to 20 24 to 30
The answer is a² + 6. "Sum of a squared and 6" means you square a value and then add 6 to it.
