Answer:
3x - 2 = 4x + 5
3x - 4x = 2 + 5 (move the numbers with the variable x to one side, and the normal numbers to the other side. Switch the signs of the numbers you move. 4x became -4x and -2 became 2.)
-x = 7 (simply add the numbers)
x = 7
A(-7,4) and B(0,6);
A(x₁,y₁) and B(x₂,y₂)
Equation form : y =mx+b
1st Calculate the slope m:
m=(y₂-y₁)/(x₂-x₁) = (6-4)/(0+7), m = 2/7
the equation becomes: y= 2/7.x +b
2nd Calculate b. to that end you plug any coordinates (either A or B) in the equation y=2/7.x + b:
Let's say I selected B(0,6)
6=2/7(0) +b and b =6
The final equation : y =(2/7).x + 6

Answer:
2 + 3i, midpoint is (2,3)
Step-by-step explanation:
we need to find the midpoint between (-1+9i) and B=(5-3i)
To find the midpoint of two points (a+bi) and (c+di) in a complex plane,
we apply formula
A = (-1+9i) and B=(5-3i)
Midpoint for AB is
2 + 3i , so midpoint is (2,3)
