Find the [tex]$x$[/tex]-intercept and the [tex]$y$[/tex]-intercept without graphing. Write the coordinates of each intercept.

When typing the point [tex]$(x, y)$[/tex], be sure to include parentheses and a comma between your [tex]$x$[/tex] and [tex]$y$[/tex] components. Do not put any spaces between your characters. If a value is not an integer, type your answer rounded to the nearest hundredth.

Given the equation:
[tex]\[ 3x + 8y = 24 \][/tex]

The [tex]$x$[/tex]-intercept is [tex]$\square$[/tex]

The [tex]$y$[/tex]-intercept is [tex]$\square$[/tex]

Let's find the [tex]$x$[/tex]-intercept and [tex]$y$[/tex]-intercept of the equation [tex]\(3x + 8y = 24\)[/tex].

### Finding the [tex]$x$[/tex]-Intercept:

The [tex]$x$[/tex]-intercept is the point where the line crosses the [tex]$x$[/tex]-axis. At this point, the value of [tex]$y$[/tex] is [tex]$0$[/tex].

1. Substitute [tex]\(y = 0\)[/tex] into the equation:
[tex]\[ 3x + 8(0) = 24 \][/tex]
which simplifies to
[tex]\[ 3x = 24. \][/tex]

2. Solve for [tex]$x$[/tex]:
[tex]\[ x = \frac{24}{3} = 8. \][/tex]

So, the [tex]$x$[/tex]-intercept is [tex]\(x = 8\)[/tex].

### Finding the [tex]$y$[/tex]-Intercept:

The [tex]$y$[/tex]-intercept is the point where the line crosses the [tex]$y$[/tex]-axis. At this point, the value of [tex]$x$[/tex] is [tex]$0$[/tex].

1. Substitute [tex]\(x = 0\)[/tex] into the equation:
[tex]\[ 3(0) + 8y = 24 \][/tex]
which simplifies to
[tex]\[ 8y = 24. \][/tex]

2. Solve for [tex]$y$[/tex]:
[tex]\[ y = \frac{24}{8} = 3. \][/tex]

So, the [tex]$y$[/tex]-intercept is [tex]\(y = 3\)[/tex].

### Writing the Coordinates of Each Intercept:

- The coordinates of the [tex]$x$[/tex]-intercept are [tex]\((8,0)\)[/tex].
- The coordinates of the [tex]$y$[/tex]-intercept are [tex]\((0,3)\)[/tex].

In summary:
- The [tex]$x$[/tex]-intercept is [tex]\(8\)[/tex]
- The [tex]$y$[/tex]-intercept is [tex]\(3\)[/tex]
