The point
(but there is literally an infinite number of possible points)
Explanation:
The lines are parallel so they will have the same gradient (slope). First we find the gradient of the first line:
To find the y-intercept we can write the equation of the line in gradient-intercept form:
We rearrange this equation and plug in the
The equation of the second line, then, is
Let's use
