which of the following is a solution to the equation y = 3x - 1
A.(4,1)
B.(2,5)
C.(4,3)
D.(0,-3)
Answer: A
No.
4 does not = 3 - 1
Okay I say D?
No.
0 does not = -9 - 1
I don't see any correct answer.
Please make sure your problem is stated correctly. Look for typos.
y = 3x - 1
for (2,5)
LS = 5
RS = 3(2) - 1 = 5
To determine which of the given options is a solution to the equation y = 3x - 1, we need to substitute the values of x and y from each option into the equation and see if they satisfy it.
For option A, the coordinates are (4,1).
Substituting x = 4 and y = 1 into the equation y = 3x - 1:
1 = 3(4) - 1
1 = 12 - 1
1 = 11
Since 1 is not equal to 11, option A is not a solution to the equation.
Let's check option B.
For option B, the coordinates are (2,5).
Substituting x = 2 and y = 5 into the equation y = 3x - 1:
5 = 3(2) - 1
5 = 6 - 1
5 = 5
Since 5 is equal to 5, option B is a solution to the equation.
Now let's check option C.
For option C, the coordinates are (4,3).
Substituting x = 4 and y = 3 into the equation y = 3x - 1:
3 = 3(4) - 1
3 = 12 - 1
3 = 11
Since 3 is not equal to 11, option C is not a solution to the equation.
Finally, let's check option D.
For option D, the coordinates are (0,-3).
Substituting x = 0 and y = -3 into the equation y = 3x - 1:
-3 = 3(0) - 1
-3 = 0 - 1
-3 = -1
Since -3 is not equal to -1, option D is not a solution to the equation.
Therefore, the only solution to the equation y = 3x - 1 is option B, (2,5).
