ANSWER
The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.
EXPLANATION
The given functions are:
f(x)=5x-1
g(x)=4x-8
To solve the equation 5x−1=4x−8 graphically, we need to graph f(x)=5x-1 and g(x)=4x-8 on the same graph sheet.
The x-coordinates of the point of intersection of the graphs of the two functions is the solution to the equation:
5x−1=4x−8
The third choice is correct.
