Answer:
Linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.
Step-by-step explanation:
If we have two linear functions f(x) and g(x) which are intersecting at a point (a,b), then equating both functions we get a linear equation as
[tex]f(x)=g(x)=y[/tex]
On solving this linear equation we get the x-coordinate of the point of intersection, i.e., x=a.
After that, we need to substitute x=a in either f(x) or g(x) to get the y-coordinate of the point of intersection.
Therefore, the linear equation formed by equating both functions is used to find the x-coordinate of the intersection point.
