Answer:
No.
Step-by-step explanation:
To figure this out, you'll need to plug in the x and y values with -2 and 9. Remember, you'll put -2 for x and 9 for y because coordinates are (x, y).
1. Plugging x and y in: 4(-2) + 3(9) > 20
2. Multiply: -8 + 27 > 20
REMEMBER- a negative times a positive will always be a negative!
3. Add: 19 > 20
NOTE- whenever you have a greater positive number being added to a negative number, it's basically just a subtraction problem now.
Now that it's simplified, we can see that 19 is not greater than 20, so it's false.
Also, if you wanted to see it graphed, I'll also put a picture of that. Just remember that if it's graphed, the point should be in the shaded part if it works. This graph shows that it isn't so this is an extra point that it is false.
