So, if you’re only given the y coordinate in your problem, you would plug that back into your equation
y=5x-1 turns into
4=5x-1 and you can solve by
5=5x
1=x
so the ordered pair turns out to be
(1,4)
In this exercise we will use the knowledge of equation of the line plus the knowledge of logarithm, like this:

First, we have the following values informed, such as:
Knowing that the formula for the equation of the line is given by:

The logarithm form will be:
