Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 8 ← is in slope- intercept form
with slope m = - 3
Parallel lines have equal slopes, then
y = - 3x + c ← is the partial equation
To find c substitute (2, - 1) into the partial equation
- 1 = - 6 + c ⇒ c = - 1 + 6 = 5
y = - 3x + 5 ← equation of line
Find y by maybe Pulling out like terms :
<span> 1.1 </span> Pull out like factors :
-y - 3 = -1 • (y + 3)
<span>Equation at the end of step 1 :</span><span>Step 2 :</span>Solving a Single Variable Equation :
<span> 2.1 </span> Solve : -y-3 = 0<span>
</span>Add 3 to both sides of the equation :<span>
</span> -y = 3
Multiply both sides of the equation by (-1) : y = -3
One solution was found : y = -3

Answer:
-3-i is the midpoint
Step-by-step explanation:
To find the real coordinate of the midpoint add the real coordinates together and divide by 2
(6+ -12)/2 = -6/2 = -3
To find the imaginary coordinate of the midpoint add the imaginary coordinates together and divide by 2
(3+-5)/2 = -2/2 =-1
-3-1i
-3-i is the midpoint
