I have already solved for the vertex, and I am trying to figure out the vertex form of an equation, how do I figure out another y intercept so that I can finish the equation y = a(x-2)^2-63 and solve for "a"? Please explain step-by-step. Will give brainliest. Thanks!

Ataxi company charges $2.25 for the first mile and then $0.20 per mile for each additional mile, or f = $2.25 + $0.20(m - 1) where f is the fare and m is the number of miles. if juan's taxi fare was $6.05, how many miles did he travel in the taxi? if juan's taxi fare was 7.65, how many miles did he travel in taxi
