The coordinate of the midpoint of segment ab is (-4, 3). find the coordinate of a if the coordinate of b is (0, 3). a = (-8, 3) (-2, 3) (4, 3)

The Y values are the same, so the Y value for A would also be 3.

B is at x 0 and the midpoint is -4 so there are 4 units between the mid point and B. You need to subtract 4 units from the midpoint for A.

-4 - 4 = -8

Point A is located at (-8,3)

(-8, 3)

Step-by-step explanation:

The formula for getting the midpoint of a line is;

midpoint = (x₁ + x₂)/2 , (y₁ + y₂)/2

(x₁,y₁) is the coordinate of A and

(x₂, y₂) is coordinate of B.

 (x₁ + 0)/2 = -4

x₁ = -4 × 2

   = -8

(y₁ + y₂)/2 = 3

y₁ + 3 = 6

y₁ = 6 - 3

    = 3

The coordinate of the A is (-8, 3)

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x
