Solution
-
Abre Excel y copia y pega los datos en una hoja de cálculo. Asegúrate de que los datos estén organizados en dos columnas, una para los valores de x y otra para los valores de y.
-
Selecciona los datos y ve a la pestaña "Insertar". Luego, selecciona "Gráfico de dispersión" y elige el tipo de gráfico de dispersión sin líneas.
-
Una vez que el gráfico esté creado, haz clic derecho en uno de los puntos de datos y selecciona "Agregar línea de tendencia".
-
En el panel de opciones de la línea de tendencia, selecciona "Lineal" y asegúrate de marcar la casilla "Mostrar ecuación en el gráfico".
-
La ecuación de la línea de tendencia aparecerá en el gráfico. La ecuación que deberías obtener es: 𝑦=2.5𝑥+3.5.
Por lo tanto, la respuesta correcta es: 𝑦=2.5𝑥+3.5.
