Question

1. Find the slope and write the equation in Point-Slope Form.

a. A (3, 4) B (5, 8)
b. C (-2, 1) D (3, 6)

*Note: when writing the equation, YOU CANNOT use the second pair of coordinates.

Answer 1

Respuesta:

y=2x-2

Explicación paso a paso:

a. A (3, 4) B (5, 8)

Pendiente (m)  

m =y₂ -y₁/x₂-x₁ =8-4/5-3 =2

he equation in Point-Slope Form.

y =mx +b

desarrollando ; tomando el Punto A(3, 4)

y-y₁=2(x-x₁)

y-4=2(x-3)

y-4=2x-6

y=2x-2
