(0, 6)

(3, 0)

(6, -6)

==============================================

Step-by-step explanation:

The first point given is (0, _) where we don't know what goes in the blank just yet. Let's call this unknown y. The point is (0, y)

Plug in x = 0 to solve for y.

2x+y = 6

2*0+y = 6

0+y = 6

y = 6

Therefore, the point is (0,6) which is the y intercept. This is where the graph crosses the y axis.

------------------------

Next we move onto (_,0)

Plug in y = 0 to find x

2x+y = 6

2x+0 = 6

2x = 6

x = 6/2

x = 3

The point (_, 0) updates to (3,0) which is the x intercept. This is where the graph crosses the x axis.

------------------------

Lastly, we'll use y = -6 to find x.

2x+y = 6

2x-6 = 6

2x = 6+6

2x = 12

x = 12/2

x = 6

We go from (_, -6) to (6, -6)

------------------------

We can use a graphing tool like Desmos to visually confirm the answers. See below.
