Linear inequality in two variables
Start
1/5
Which of the following is a linear inequality in two variables?
2x + 3y = 64
4x - y < 18
10xy > 31
right answer
The degree of the inequality is 1 and the symbol used is an inequality symbol (<) .
2/5
Determine if the ordered pair (-1, 2) is a solution or not of 5x - y 13.
NOT THE SOLUTION
SOLUTION
MAYBE
right answer
When you substitute the given ordered pair and simplify it further, the answer would be -7 13 so it is a SOLUTION.
3/5
One of the solutions of the linear inequality 8y + 2x > 42 is (4, 2).
FALSE
MAYBE
TRUE
right answer
When you substitute the given ordered pair and simplify it further, the answer would be 24 > 42, so it is NOT A SOLUTION/FALSE.
4/5
Which of the following is the solution of 2y < 6x + 12?
( -3, 2 )
( 3, 7 )
( 1, 9 )
right answer
If you substitute the ordered pair ( 3, 7 ) in the given linear inequality, the answer would be 14 < 30 which is correct.
5/5
Which of the following will satisfy 4x + 9y > 36?
( 4, 3 )
( 3, -1 )
( -3, 4 )
right answer
If you substitute the ordered pair ( 4, 3 ) in the given linear inequality, the answer would be 43 > 36 which is correct.
