The output (y) for an input (x) of 2 in the equation y = 3x - 5 is 1.

We are given the equation y = 3x - 5 and we need to find the output (y) for an input (x) of 2.

Step 1: Substitute the value of x with 2 in the equation:

y = 3(2) - 5

Step 2: Simplify the equation:

y = 6 - 5

Step 3: Perform the subtraction:

y = 1

Therefore, when we input x = 2 into the equation y = 3x - 5, the output (y) is 1.

To further understand how we arrived at this answer, let's break it down:

In the equation y = 3x - 5, the coefficient of x is 3. This means that for every increase of 1 in the value of x, the value of y increases by 3.

So, when we substitute x = 2 into the equation, we have:

y = 3(2) - 5

y = 6 - 5

y = 1

This means that when x is 2, y is 1. In other words, if we were to plot the points on a graph where the x-coordinate is 2, the y-coordinate would be 1.

Therefore, the output (y) for an input (x) of 2 in the equation y = 3x - 5 is 1.
