graph{x-3 [-0.392, 4.62, -3.096, -0.59]}

Explanation:

We can express any linear equation in two variables
in the form
xa+yb=1
(here the eq will be (xayb=3)
1.we want to find where the line intersects the y axis

  1. automatically the value of x will become 0
    we are left with yb=3
    by putting b=1 we get y=3
    the line intersects the y axis at (0,3)
  2. in the same way we can also find out here the line intersects the axis
    it will be (3,0)

in terms of plotting the equation we will mark the two
points on the x&y and draw a st line through them
