Step-by-step explanation:
We know that , Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. Solution of any two linear equations is the intersection point of graph of both linear functions , as wherever they intersect they have the same value of function for the same value of x , Also by substitution method or normally we solve two linear equations and we get value of x & y which is similar to proceeding through intersection point of both linear functions graph. See the give picture below for good reference!
