Question

How do you graph `x-y=3` using the x and y intercepts?

Answer 1

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

Explanation:

We can express any linear equation in `two` variables
in the form
`x/a`+`y/b`=`1`
(here the `eq` will be (`x/a` `-y/b`=`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 `-` `y/b`=`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`
