It is called the point of intersection. It will also be the value that satisfies the equation F(x)=G(x) were F and G of x are functions( that are intersecting).
No, it is called an intercept.
In the context of two parallel lines and an intercept, they are called interior angles.
Intercept
Unless they are the exact same lines, no. Parallel lines do not touch. If two lines have the same intercept value, they share a point, and therefore touch.
Knowing that they have the same y-intercept, and knowing nothing else, the only thing you can say about the two lines is that they have the same y-intercept. That fact doesn't tell you anything else about them.

Because a linear function just has to be a strait line which is not vertical at any point (stait), the two lines can be positioned anywhere on a graph with the same y intercepts. For instance, you could have a big "x" on the graph, where the lines cross on the y line, and have their y intercepts be the same.

a double line graph is a graph that is same as a line graph but there are two lines
When two lines intersect on a graph, their equations represent systems of linear equations. At the point of intersection, the coordinates satisfy both equations simultaneously, meaning that the x and y values are the same for both lines. Mathematically, this is often found by setting the two equations equal to each other and solving for the variable, which gives the intersection point. If the lines are parallel, they do not intersect, while if they are coincident, they intersect at infinitely many points.
If you want to graph parallel lines, they need to have the same slope (Ex. 2x+2 and 2x+3)- parallel lines cannot have the same y-intercept because the two line would be the same. Perpendicular lines slopes need have to be opposite reciprocals (Ex. -2x+4 and +1/2x+3)- perpendicular lines can have the same y-intercepts, it doesn't make a difference.
