Now, let's work through each step:
Step 1: The equation provided is $y = \frac{1}{2}x$. We need to find the value of $y$ when $x = 2$.
Step 2: Substitute $x = 2$ into the equation:

$y = \frac{1}{2} \times 2$

To solve the problem, we will follow these steps:

• Step 1: Substitute the given value of $x$ into the equation $y = x - 8$.

• Step 2: Simplify the expression to find the corresponding value of $y$.

Now, let's apply these steps:

Step 1: Given the equation $y = x - 8$, we substitute $x = 2$:
$\begin{aligned} y &= 2 - 8 \end{aligned}$

Step 2: Simplify the expression:
$\begin{aligned} y &= -6 \end{aligned}$

Thus, the value of $y$ when $x = 2$ is $-6$.

Therefore, the solution to the problem is $y = -6$.

Now, let's work through each step:
Step 1: The problem gives us that $x = 2$ and the relationship between $y$ and $x$ is $y = 0.8x$.
Step 2: We will use the formula $y = 0.8 \times x$.
Step 3: Substituting $x = 2$ into the formula, we get $y = 0.8 \times 2$.

The calculation is as follows:
$y = 0.8 \times 2 = 1.6$.

Therefore, the solution to the problem is $y = 1.6$.

To solve this problem, we'll follow these steps:

• Substitute the given value of $x$ into the equation $y = 30x - 6$.

• Perform the necessary arithmetic to solve for $y$.

Now, let's work through these steps:
Step 1: The problem gives us $x = 2$ and the equation $y = 30x - 6$.
Step 2: Substitute $x = 2$ into the equation:
$y = 30(2) - 6$

Step 3: Calculate the expression:
$\begin{aligned} y &= 30 \times 2 - 6 \\ y &= 60 - 6 \\ y &= 54 \end{aligned}$

The solution to the problem is $y = 54$.

To solve this problem, we’ll follow these steps:

• Step 1: Substitute the given value of $x$ into the equation.
• Step 2: Perform the arithmetic calculation to find $y$.

Let’s work through each step:

Step 1: Our given equation is $y = 8x + 1$. We substitute $x = 2$ into the equation:

$y = 8(2) + 1$

Step 2: Calculate the expression:

$y = 16 + 1$

$y = 17$

Therefore, when $x = 2$, the value of $y$ is $17$.

To solve for $y$, we will proceed with these steps:

• Step 1: Substitute the given value $x = 2$ into the equation $y = 4(2 - 6x)$.
• Step 2: Simplify the expression inside the parentheses.
• Step 3: Perform the arithmetic operations to find $y$.

Now, let's work through the steps:

Step 1: Substitute $x = 2$ into the equation:
$y = 4(2 - 6 \times 2)$

Step 2: Simplify the expression within the parentheses:
$2 - 6 \times 2 = 2 - 12 = -10$

Step 3: Calculate the value of $y$ by multiplying by 4:
$y = 4 \times (-10) = -40$

Therefore, the value of $y$ is $-40$.

This solution corresponds to the choice:

Choice 3: $-40$

To solve this problem, we need to substitute $x = 2$ into the given expression for $y$.

• Step 1: Write down the expression for $y$: $y = 18(x - 2)$.
• Step 2: Substitute $x = 2$ into the expression.
• Step 3: Simplify the expression.

Let's perform these steps:

Step 1: The expression given is $y = 18(x - 2)$.

Step 2: Substitute $x = 2$ into the expression:
$y = 18(2 - 2)$.

Step 3: Simplify the expression:
Since $2 - 2 = 0$, we have $y = 18 \times 0 = 0$.

Therefore, when $x = 2$, the value of $y$ is $0$.

In this exercise, we are given the value of X, so we will substitute it into the formula.

It's important to remember that between an unknown and a number there is a multiplication sign, therefore:

$y=\frac{2}{5}\cdot(2)+2$

$y=\frac{4}{5}+2$

Let's convert to a decimal fraction:

$y=0.8+2$
$y=2.8$

And that's the solution!

To solve this problem, follow these steps:

• Step 1: Identify the given equation and variable.
• Step 2: Substitute the given value of $x$ into the equation.
• Step 3: Perform the necessary arithmetic to calculate $y$.

Now, let's work through each step:
Step 1: The equation given is $y = 5.6x - 2.1$. We need to find $y$ when $x = 2$.
Step 2: Substitute $x = 2$ into the equation:
$y = 5.6(2) - 2.1$.
Step 3: Calculate $y$ by performing the arithmetic:
First, calculate the multiplication: $5.6 \times 2 = 11.2$.
Then, subtract 2.1 from 11.2: $11.2 - 2.1 = 9.1$.

Therefore, the solution to the problem is $y = 9.1$.

To solve this problem, we'll substitute the given value of $x = 2$ into the equation $y = 2 + 6x$.
1. Substitute $x = 2$ into the equation:
$\begin{aligned} y &= 2 + 6x \\ &= 2 + 6 \times 2 \end{aligned}$

2. Perform the multiplication $6 \times 2$:
$6 \times 2 = 12$

3. Add the result to 2:
$\begin{aligned} y &= 2 + 12 \\ &= 14 \end{aligned}$

Thus, when $x = 2$, the value of $y$ is $\mathbf{14}$.
