Answer:

  • See below

Explanation:

Given:

  • Line y = 2x + 1

There are two ways of finding if the points belong to the graph:

1. Graph the line and plot the points and confirm visually.

  • This is added for you, see attached
  • Green line and green points are those given. It is visible all points are on the line apart from two of them: (0.5, 1) and (2, -1)
  • The red points are additional ones

2. Plug in the values into equation and confirm.

  • You have done couple of them and this can be continued to all listed points.
  • Additional points are calculated same way.
