Final answer:
The question involves plotting points and drawing lines or vectors on a coordinate plane, although the full context of the question is unclear due to typos.
Step-by-step explanation:
The student seems to be asking about plotting points and drawing lines on a coordinate plane. It's unclear what the full question is, but the focus appears to be on performing operations with vectors or lines on a graph.
To plot the points (-3,-7) and (-7,-1), you would find each point on the coordinate plane and mark them. Then, to draw a line segment between these two points, use a ruler to connect them with a straight line.
When working with vector addition, such as adding a 9-unit eastward vector to a 5-unit northward vector, you would place the first vector on the graph, then attach the tail of the second vector to the head of the first and draw the resulting vector.
