Answer 1

To find the graph of a line we need two points on the plane.

I f we have the equation of the line:

`y=(2)/(9)x+3`

we need to give values to x (whichever values we like), and then find the value of y; this will give us one point.

Let x=0, then:

`y=(2)/(9)(0)+3=0+3=3`

Then we have the point (0,3).

Now we need another point, let x=9. Then:

`y=(2)/(9)(9)+3=2+3=5`

Then we have the point (9,5).

Once we have two points we plot them on the plane:

Now that we plot the two points we joined them with a straight line to get the graph of the line:
