STEP 1
What is this asking?
We're figuring out if some lines are horizontal or vertical and then drawing a few of them!
Watch out!
Don't mix up *x* and *y*!
A horizontal line is all about *y* and a vertical line is all about *x*.
STEP 2
1. Classify the lines
2. Graph the lines
STEP 3
Alright, for problem **23**, we've got .
Since *y* is always no matter what *x* is, this is a **horizontal** line!
STEP 4
Next up, problem **24**: .
This time, *x* is locked in at **3**, regardless of what *y* does.
That means it's a **vertical** line!
STEP 5
Finally, problem **25**: .
Just like problem **23**, *y* is a constant value, meaning it's a **horizontal** line!
STEP 6
We're graphing .
Since *y* is always **6**, we draw a **horizontal** line that goes through the point on the *y*-axis.
Imagine it stretching forever to the left and right, always staying at .
STEP 7
Now we're graphing .
Because *x* is always , we draw a **vertical** line passing through on the *x*-axis.
This line goes straight up and down, forever, with *x* always being .
STEP 8
For , we're drawing another **horizontal** line.
This one goes through on the *y*-axis, extending infinitely left and right, always at .
STEP 9
23. **Horizontal**
24. **Vertical**
25. **Horizontal**
27. A horizontal line through .
28. A vertical line through .
29. A horizontal line through .
