For this question you can do it 2 ways. Either you can solve for b using the y=mx+b form or you can do it using point slope form.

solving for b you get
y=mx+b
2=4/3(3)+b
2=4+b
-2=b
y = 4/3x-2
using point slope form
y-y1=m(x-x1)
y-2=4/3(x-3)
y=4/3x-4+2
y=4/3x-2
either way you get the right answer
*Note point slope form is very useful later in mathematics and is used alot in calculus so keep that in mind.
