Answer:

X = 1/2y + -1/2

Y = 2x + 1

Step-by-step explanation:

How to Solve for X

Step 1: Flip the equation.

Step 2: Add -1 to both sides.

Step 3: Divide both sides by 2.

You don't need to solve for "y" because you already know what y is.

Find the coordinates of the midpoint of the segment given its endpoints.

Vesna [10]

Answer:

(2, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ $\frac{1}{2}$ (x₁ + x₂ ) , $\frac{1}{2}$ (y₁ + y₂ ) ]

Here (x₁, y₁ ) = (A(5, 8) and (x₂, y₂ ) = B(- 1, - 4) , thus

midpoint = [ $\frac{1}{2}$ (5 - 1), $\frac{1}{2}$ (8 - 4 ) ] = (2, 2 )
