Answer:
Hi there!
Your answer is:
Based off the problem we can tell that the slope is -2/3 and the y intercept is 2. This means we must start our line at the point (0,2). Since slope is in the form rise/run, we know that we must go UP 2 units for every 3 units we go LEFT! We know to go left (As x goes to positive infinity, y goes to negative infinity. ) because the slope is negative!
Hope this helps

Answer: C) integers and rational numbers</h3>
Explanation:
The set of integers is {..., -3, -2, -1, 0, 1, 2, 3, ...} basically any number that does not have a decimal or fractional part to it. We can say that this set is composed of positive and negative whole numbers along with 0. So this is why -3 is in the set of integers.
The value -3 is not in the set of whole numbers because the set of whole numbers is {0, 1, 2, 3, 4, 5, 6, ...}, so this rules out choice D.
Choice B is also eliminated because -3 is a rational number. We can write -3 as a fraction of two integers, example: -3 = -3/1. Any rational number is not irrational, and vice versa.
Choice A is ruled out because it's not the most complete answer (though its technically true).

Answer:
x = 10
y = 11
Step-by-step explanation:
Solve for x:
2x + 3y = 53
3x(3) - y(3) = 19(3)
2x + 3y = 53
9x - 3y = 57
Add:
2x = 53
9x = 57
11x = 110
Solve algebraically:
x = 110 ÷ 11
x = 10
Now solve for y:
2(10) + 3y = 53
20 + 3y = 53
3y = 53 - 20
3y = 33
y = 33 ÷ 3
y = 11
Verify for the second equation:
3x - y = 19
3(10) - (11) = 19
30 - 11 = 19
30 = 19 + 11
30 = 30 (Correct)
Cheers!
