Henderson Hasselbalch

Hi, Can anyone help me make sense of this question, don't know how to go about answering it, cheers. A Henderson Hasselbalch plot y= x+5.3, where the y-axis intercept is equal to the pKa. Calculate the pKa based on this information.

It's against the charter to just give you the solution but see if you can figure it out from what I wrote below.

If a line is wrote in the form [latex]y=mx+c[/latex], then m is the slope of the line and c is the intercept on the y axis. With that in mind, can you identify from your equation what the intercept is?
