To find an equation of a line that is parallel to the line \( y = 2x + 4 \), we need to remember that parallel lines have the same slope. The slope of the given line \( y = 2x + 4 \) is 2.
Therefore, we are looking for an equation of the form \( y = 2x + b \), where \( b \) can be any number.
Now let's analyze the options provided:
- \( y = 2x - 7 \): This has the same slope (2) and is therefore parallel.
- \( y = \frac{1}{2}x - 3 \): This has a slope of \( \frac{1}{2} \), which is not parallel.
- \( y = -\frac{1}{2}x + 4 \): This has a slope of \( -\frac{1}{2} \), which is not parallel.
- \( y = -2x + 2 \): This has a slope of \( -2 \), which is also not parallel.
The only equation that fits the criteria of being parallel to \( y = 2x + 4 \) is:
\( y = 2x - 7 \).
