Question

  1. draw a point a= (-5, 6)
  2. draw a point b = (3, 1)
  3. draw a line from a to b
  4. what is the x value change from a to b? (x2 - x1)

( )

  1. what is the y value change? from a to b?(y2 - y1)

( )

  1. what is the length of line ab

distance ab = √((x2 - x1)² + (y2 - y1)²) =
( )

Explanation:

Step1: Identificar valores de x

Sean $x_1=-5$ (coordenada x de A) y $x_2 = 3$ (coordenada x de B). Calculamos la diferencia $x_2 - x_1=3-(-5)=8$.

Step2: Identificar valores de y

Sean $y_1 = 6$ (coordenada y de A) y $y_2=1$ (coordenada y de B). Calculamos la diferencia $y_2 - y_1=1 - 6=-5$.

Step3: Calcular longitud de AB

Usamos la fórmula $d=\sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}$. Sustituyendo $x_2 - x_1 = 8$ y $y_2 - y_1=-5$, tenemos $d=\sqrt{8^2+(-5)^2}=\sqrt{64 + 25}=\sqrt{89}$.

Answer:

  1. 8
  2. -5
  3. $\sqrt{89}$
