Complx Number

[kaebun]

i have no clue at all what to do here....
it says if z=a+bi find a, b, |z|
there is graph that shows on the imaginary axis 4 and on the real -3 so the point is (-3,4)
I hope this description makes sence.... thanks for any help in advance

A point (m, n) on the complex plane corresponds to the complex number z = m + ni. The modulus of the number, |z|, is given by sqrt[m² + n²].
