We are asked in the problem to deterimne the point slope form that is y - y1 = m(x-x1),. Substituting, m = 3 and x1 = 2
Translating,
y + a = 3*(x-2).
Ahnswer to this problem then is C.
There is many answers to this question but angle B and C have to add up to 140 so angle B and C could both be 70 that should work
