Answer:
1. 1/2
2. (-2, 3) (there are multiple answers for this question)
3. -2
4. (-2, -2) (there are multiple answers for this question)
Explanation:
We are following the equation of Y=mx+b, m = slope and b = y-intercept
So in the equation of y = (1/2)x - 4 we know that m=1/2 and b = -4
If a line is Parallel to another it means it has the same slope
If a line is Perpendicular to another it means the slope is flipped and switched from positive to negative or negative to positive
1. So to find the slope of a parallel line on the graph we know it will be 1/2 since it is parallel and parallel lines always have the same slope
2. To find an additional point on the line you can use the slope and do rise over run (I will attach a screenshot below explaining)
3. To find the slope of a perpendicular line on the graph you need to fist flip the number so 1/2 turns into 2/1 or 2. Then you need to make the number negative so -2 would be your slope for the perpendicular line
4. To find an additional point on the line you can use the slope and do rise over run (I will attach a screenshot below explaining)
