The equation of the line is:
Explanation:
We often work with the y-intercept, but the x-intercept is less common. Still not too difficult, though.
We can write the equation of a line in standard form as:
where
We find the y-intercept by setting
Let's see whether turning that around will work: let's set
Rearranging, we get:
The overall equation of the line, then, is:
