This equation represents a linear relationship where y is equal to 3 times x minus 1. To find a solution, we need to substitute values for x and solve for y.
Let's consider some values:
When x = 0:
y = 3(0) - 1
y = 0 - 1
y = -1
When x = 1:
y = 3(1) - 1
y = 3 - 1
y = 2
So, the solution to the equation y = 3x - 1 is that (0, -1) and (1, 2) are both solutions.
Which of the following is a solution to the equation y = 3x – 1?

The equation y = 3x - 1 represents a linear relationship where y is equal to 3 times x minus 1. To determine if a given point is a solution to the equation, we substitute the values into the equation and check if both sides are equivalent.
Let's consider the options:
(4, 1):
Substituting x = 4 and y = 1 into the equation:
1 = 3(4) - 1
1 = 12 - 1
1 = 11
Since 1 is not equal to 11, (4, 1) is not a solution to the equation.
(2, 5):
Substituting x = 2 and y = 5 into the equation:
5 = 3(2) - 1
5 = 6 - 1
5 = 5
Both sides are equal, so (2, 5) is a solution to the equation.
(4, 3):
Substituting x = 4 and y = 3 into the equation:
3 = 3(4) - 1
3 = 12 - 1
3 = 11
Since 3 is not equal to 11, (4, 3) is not a solution to the equation.
(0, -3):
Substituting x = 0 and y = -3 into the equation:
-3 = 3(0) - 1
-3 = 0 - 1
-3 = -1
Since -3 is not equal to -1, (0, -3) is not a solution to the equation.
Therefore, the solution to the equation y = 3x - 1 is only given by the option (2, 5).
Let's consider the options:
(4, 1):
Substituting x = 4 and y = 1 into the equation:
1 = 3(4) - 1
1 = 12 - 1
1 = 11
Since 1 is not equal to 11, (4, 1) is not a solution to the equation.
(2, 5):
Substituting x = 2 and y = 5 into the equation:
5 = 3(2) - 1
5 = 6 - 1
5 = 5
Both sides are equal, so (2, 5) is a solution to the equation.
(4, 3):
Substituting x = 4 and y = 3 into the equation:
3 = 3(4) - 1
3 = 12 - 1
3 = 11
Since 3 is not equal to 11, (4, 3) is not a solution to the equation.
(0, -3):
Substituting x = 0 and y = -3 into the equation:
-3 = 3(0) - 1
-3 = 0 - 1
-3 = -1
Since -3 is not equal to -1, (0, -3) is not a solution to the equation.
Therefore, the solution to the equation y = 3x - 1 is only given by the option (2, 5).

To determine the equation that represents the pattern in the table, we need to analyze the relationship between Sal's and Carrie's ages.
By observing the table, we can see that Sal's age is always 2 years older than Carrie's age.
Hence, we can conclude that the equation representing the pattern is:
s = c + 2
The equation s = c + 4, s = 4c, and c = s + 4 do not match the observed relationship in the table.
Therefore, the correct equation that represents the pattern is s = c + 2.
By observing the table, we can see that Sal's age is always 2 years older than Carrie's age.

Solve. x – 6 = –18
To solve the equation x - 6 = -18, we need to isolate the variable x on one side of the equation.
To do this, we can add 6 to both sides of the equation:
x - 6 + 6 = -18 + 6
This simplifies to:
x = -12
Therefore, the solution to the equation x - 6 = -18 is x = -12.
To do this, we can add 6 to both sides of the equation:
x - 6 + 6 = -18 + 6
This simplifies to:
x = -12
Therefore, the solution to the equation x - 6 = -18 is x = -12.

Let's represent the number of t-shirts you can buy as x.
The cost of each t-shirt is $11, and you have a coupon for $6 off. This means the effective cost of each t-shirt after using the coupon is $11 - $6 = $5.
Since you have $27 to spend at the mall, we can set up the equation:
$5x = $27
To find x, we divide both sides of the equation by $5:
x = $27 / $5
Simplifying the division:
x = 5.4
However, since we can't purchase a fraction of a t-shirt, we round down to the nearest whole number.
You can buy 5 t-shirts using your coupon and money.
Hence, the correct solution is 5 shirts.
The cost of each t-shirt is $11, and you have a coupon for $6 off. This means the effective cost of each t-shirt after using the coupon is $11 - $6 = $5.
