Which equation contains the point (2, 13)?
A
5x + 3 = y
B
6x - 2 = y
C
3x + 5 = y
D
7x - 10 = y
To determine which equation contains the point (2, 13), substitute the x-coordinate (2) into each equation and check if the resulting y-coordinate matches with the y-coordinate (13).
A) For equation A: 5(2) + 3 = 13, which is true.
B) For equation B: 6(2) - 2 = 10, which is not true.
C) For equation C: 3(2) + 5 = 11, which is not true.
D) For equation D: 7(2) - 10 = 4, which is not true.
Therefore, the equation that contains the point (2, 13) is equation A: 5x + 3 = y.
Which equation contains the point (2, 7)?
A
2x + 1 = y - 2
B
x + 4 = y
C
3x + 5 = y
D
2x + 1 = y
To determine which equation contains the point (2, 7), substitute the x-coordinate (2) into each equation and check if the resulting y-coordinate matches with the y-coordinate (7).
A) For equation A: 2(2) + 1 = 4 + 1 = 5, which is not true.
B) For equation B: 2 + 4 = 6, which is not true.
C) For equation C: 3(2) + 5 = 6 + 5 = 11, which is not true.
D) For equation D: 2(2) + 1 = 4 + 1 = 5, which is not true.
Therefore, none of the given equations contain the point (2, 7).
Choose all selections that represent the domain of the relation, {(2, 5)(3, 6)(2, 8)}
{2, 2, 3}
{2, 3, 6}
{5, 6, 8}
{2, 3}
{2, 3, 5, 6, 8}
The domain of a relation is the set of all the x-values in the relation.
In the given relation, {(2, 5)(3, 6)(2, 8)}, the x-values are 2 and 3.
Therefore, the correct selection that represents the domain of the relation is {2, 3}.
There is more than one answer. Please select again.
Apologies for the confusion. You are correct, there is more than one answer.
The x-values in the relation {(2, 5)(3, 6)(2, 8)} are 2 and 3.
Therefore, the selections that represent the domain of the relation are {2, 3} and {2, 3, 5, 6, 8}.
Which equation contains the point (2, 6)?
A
3x + 5 = y
B
2x + 1 = y
C
x + 4 = y
D
2x + 1 = y - 2
To determine which equation contains the point (2, 6), substitute the x-coordinate (2) into each equation and check if the resulting y-coordinate matches with the y-coordinate (6).
A) For equation A: 3(2) + 5 = 6 + 5 = 11, which is not true.
B) For equation B: 2(2) + 1 = 4 + 1 = 5, which is not true.
C) For equation C: 2 + 4 = 6, which is true.
D) For equation D: 2(2) + 1 = 4 + 1 = 5, which is not true.
Therefore, the equation that contains the point (2, 6) is equation C: x + 4 = y.
