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.
A linear equation is a special type of function. The majority of functions are not linear.
they express linear equations in a visible way
