Question

Drawing it out would be best can you help me please

Answer 1

`z_1+z_2` = (-2,5)

Explanation:

To Find:
`z_1+z_2`

Solution :

Referring the given graph

We can find the coordinates of
`z_1` and
`z_2`

Coordinates of
`z_1`= (-7,1)

Coordinates of
`z_2`= (5,4)

Thus Coordinates of
`z_1+z_2` = (-7+5,1+4) = (-2,5)

Thus
`z_1+z_2` = (-2,5)

So, the point
`z_1+z_2` = (-2,5) is shown on the attached graph file
