What are the coordinates of B
Kitty [74]

The coordinates of B are (14, -10).

<h3>How to find mid point?</h3>

The midpoint is already know . we can use it to find the coordinates of B.

Therefore,

(xₙ, yₙ) = (x₁ + x₂ / 2, y₁ + y₂ / 2)

Hence,

M(5, - 4) and A(-4, 2)

The coordinates of B are as follows:

(5, - 4)  = (-4 + x₂ / 2 , 2 + y₂ / 2)

5 = -4 + x₂ / 2

10 = -4 + x₂

x₂ = 14

hence,

-4 = 2 + y₂ / 2

-8  = 2 + y₂

y₂ = - 10

Therefore, the coordinates of B are (14, -10)

Plz help me agh! It’s linear stuff
kherson [118]

Answer:

(1/2)x - y = -2

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Equality Properties

<u>Alg I</u>

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Standard Form: Ax + By = C

Step-by-step explanation:

<u>Step 1: Define equation</u>

Slope-Intercept Form: 2 + (1/2)x = y

<u>Step 2: Find Standard Form</u>

  1. Rewrite:                                        y = (1/2)x + 2
  2. Subtract 1/2x on both sides:       y - 1/2x = 2
  3. Factor negative:                          -(1/2x - y) = 2
  4. Divide both sides by -1:               1/2x - y = -2
