Match points of the complex plan and complex numbers Algebra II

Let a and b be two real numbers. The complex number z=a+ib is represented on the complex plan by the point A\left(a,b\right).

Here we have:

z_1=-2+3i

Therefore z_1 is represented by A_1\left(-2{,}3\right) :

Let a and b be two real numbers. The complex number z=a+ib is represented on the complex plan by the point A\left(a,b\right).

Here we have:

z_1=-1+2i

Therefore z_1 is represented by A_1\left(-1{,}2\right) :

Let a and b be two real numbers. The complex number z=a+ib is represented on the complex plan by the point A\left(a,b\right).

Here we have:

z_1=10-5i

Therefore z_1 is represented by A_1\left(10,-5\right) :

Let a and b be two real numbers. The complex number z=a+ib is represented on the complex plan by the point A\left(a,b\right).

Here we have:

z_1=7+8i

Therefore z_1 is represented by A_1\left(7{,}8\right) :

Let a and b be two real numbers. The complex number z=a+ib is represented on the complex plan by the point A\left(a,b\right).

Here we have:

z_1=-4+7i

Therefore z_1 is represented by A_1\left(-4{,}7\right) :

Let a and b be two real numbers. The complex number z=a+ib is represented on the complex plan by the point A\left(a,b\right).

Here we have:

z_1=12+2i

Therefore z_1 is represented by A_1\left(12{,}2\right) :

Let a and b be two real numbers. The complex number z=a+ib is represented on the complex plan by the point A\left(a,b\right).

Here we have:

z_1=-25+7i

Therefore z_1 is represented by A_1\left(-25{,}7\right) :
