Answer:
Explanation:
1. We know that a line that is parallel to another line will have no solutions, so the slopes have to be the same but the y-intercept needs to be different.
2. So, we would get y=-1/4x+4 for a parallel line.
3. For a line that is perpendicular to your line, there has to be one solution so that they intersect, so the slopes have to be different.
4. So, we would get y=-1/2x+1 for a perpendicular line.
I'm pretty sure this is correct, if it is wrong just please let me know and I'll remove it. Thank you.
