Answer: Plot a straight line through (5,4) and (8,2)
See diagram below.
=================================================
Step-by-step explanation:
Start at the given point (5,4)
The slope -2/3 means we go down 2 and then right 3.
So if we go down 2 units then we go from (5,4) to (5,2). Then move 3 units to the right to get to (8,2)
The two points (5,4) and (8,2) are on the line.
See the diagram below. I used GeoGebra, but Desmos is another good option.
