Answer:
A, D
Step-by-step explanation:
Sub the x and y values into the equation. The x value is the first number in the coordinate, and the y value is the second number.
If the left side is equal to the right side, it is a solution.
Example:
4x-5y=24
4(-9)-5(-12)=24
-36+60=24
24=24
Remember: if the left side does not equal the right side, it is not a solution.
Instead of adding or subtracting 2pi (that's for radians only), just add or subtract 360 degrees to your angle.
