HELPPPPPPPPPPPPP idk what to do

A titration was carried out to measure the concentration of ethanoic acid in a sample of vinegar. 25cm3 of a vinegar solution was titrated with a solution of NaOH, concentration 0.250. The concentration of the ethanoic acid in the vinegar solution was found to be 0.125.

pH of ethanoic acid - 2.84
Half neutralisation pH - 4.77
NaOH pH - 13.4

What would titration curve look like when 30cm of NaOH is added to 25cm of the vinegar solution with NaOH being on x axis and pH on y axis?
