Y is the midpoint of AB, The coordinates are A(-3,-7) and B(-1,1) What is the coordinate Y?

NISA [10]

The formla of a midpoint of AB:

$M\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)$

We have A(-3, -7) and B(-1, 1). Substitute:

$x_M=\dfrac{-3+(-1)}{2}=\dfrac{-4}{2}=-2\\\\y_M=\dfrac{-7+1}{2}=\dfrac{-6}{2}=-3$

<h3>Answer: M(-2, -3)</h3>

1. Write an equation in point slope form for the line that has a slope of 6 and contains the point (-8,-7).

antiseptic1488 [7]

1. y - y₁ = m(x - x₁)
 y - (-7) = 6(x - (-8))
 y + 7 = 6(x + 8)
 y + 7 = 6(x) + 6(8)
 y + 7 = 6x + 48
 - 7 - 7
 y = 6x + 41

2. y₂ - y₁ = -8 - (-3) = -8 + 3 = -5 = -1²/₃
 x₂ - x₁ -1 - (-4) -1 + 4 3

3. 2x - 3y = 11
 3x + 3y = 9
 5x = 20
 5 5
 x = 4
 2x - 3y = 11
 2(4) - 3y = 11
 8 - 3y = 11
 - 8 - 8
 -3y = 3
 -3 -3
 y = -1
 (x, y) = (4, -1)

4. 2x - 5y = -7 ⇒ -6x + 15y = 21
 5x - 3y = 11 ⇒ -25x + 15y = -55
 19x = 76
 19 19
 x = 4
 2x - 5y = -7
 2(4) - 5y = -7
 8 - 5y = -7
 - 8 - 8
 -5y = -15
 -5 -5
 y = 3
 (x, y) = (4, 3)

5. 4.9 × 10¹¹, 8.9 × 10¹⁸, 1.3 × 10⁸, 6.7 × 10⁸, 2.7 × 10⁸
 1.3 × 10³, 2.7 × 10⁸, 6.7 × 10⁸, 4.9 × 10¹¹, 8.9 × 10¹⁸
