They are not. A vertical line is not a function so all linear equations are not functions. And all functions are not linear equations.
Linear equations are a small minority of functions.
Most functions are not like linear equations.
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
YES, all linear equations have x-intercepts. because of the x, y has to be there 2!
All linear equations are functions but not all functions are linear equations.

Linear equations are always functions.
Linear equations are a tiny subset of functions. Linear equations are simple, continuous functions.

Normally no. But technically, it is possible if the two linear equations are identical.
When two linear functions share the same rate of change, their graphs will be parallel lines because they have the same slope. However, their equations will differ in the y-intercept, which means they will cross the y-axis at different points. Consequently, their tables of values will show consistent differences in their outputs for the same inputs. Despite having the same slope, these differences lead to distinct linear functions.
