what is an equation of the line that passes through the points $(-4,1)$ and $(4,-1)$?

what is an equation of the line that passes through the points $(-4,1)$ and $(4,-1)$?

Answer

Explanation:

Step1: Calcular la pendiente

La fórmula de la pendiente (m) entre dos puntos ((x_1,y_1)) y ((x_2,y_2)) es (m=\frac{y_2 - y_1}{x_2 - x_1}). Dados los puntos ((-4,1)) y ((4,-1)), entonces (m=\frac{-1 - 1}{4-(-4)}=\frac{-2}{8}=-\frac{1}{4})

Step2: Usar la ecuación punto - pendiente

La ecuación punto - pendiente es (y - y_1=m(x - x_1)). Tomemos el punto ((-4,1)) y (m =-\frac{1}{4}). (y - 1=-\frac{1}{4}(x+4))

Step3: Simplificar la ecuación

(y - 1=-\frac{1}{4}x - 1) (y=-\frac{1}{4}x)

Answer:

(y =-\frac{1}{4}x)
