A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water:What does the y-intercept of the graph represent? There were 400 larvae at 0 degree Celsius. There were no larvae at 400 degrees Celsius. The original number of larvae in the water was 400. The original temperature of the water was 400 degrees Celsius.
Question
A biologist created the following graph to show the relationship between the temperature of water (x), in degrees Celsius, and the number of insect larvae (y) in the water:What does the y-intercept of the graph represent? There were 400 larvae at 0 degree Celsius. There were no larvae at 400 degrees Celsius. The original number of larvae in the water was 400. The original temperature of the water was 400 degrees Celsius.
Solution
Para responder a esta pregunta, sigamos los siguientes pasos:
-
Identificar el eje y y el eje x en el gráfico:
- El eje x representa la temperatura del agua en grados Celsius.
- El eje y representa el número de larvas de insectos en el agua.
-
Definir el intercepto en y:
- El intercepto en y es el punto donde la gráfica cruza el eje y. Esto ocurre cuando x = 0.
-
Interpretar el valor del intercepto en y:
- Según la información proporcionada, cuando la temperatura del agua es 0 grados Celsius (x = 0), hay 400 larvas (y = 400).
-
Determinar qué representa el intercepto en y:
- El intercepto en y representa el número de larvas cuando la temperatura del agua es 0 grados Celsius.
-
Analizar las opciones dadas:
- "There were 400 larvae at 0 degree Celsius." -> Esta opción es correcta porque coincide con la interpretación del intercepto en y.
- "There were no larvae at 400 degrees Celsius." -> Esta opción no se relaciona con el intercepto en y.
- "The original number of larvae in the water was 400." -> Esta opción podría ser confusa, pero no es tan precisa como la primera opción.
- "The original temperature of the water was 400 degrees Celsius." -> Esta opción es incorrecta porque el intercepto en y se refiere a la temperatura de 0 grados Celsius, no 400.
Por lo tanto, la respuesta correcta es: "There were 400 larvae at 0 degree Celsius."

Adrian records the number of chirps per minute ( x ) that crickets make at different temperatures ( y ).He determines that the association is linear and that the line of best fit is 𝑦=15𝑥+50y= 51 x+50.What is the interpretation of the slope and y-intercept of this equation?Click here for long descriptionA.The slope predicts a temperature increase of about 1° for every increase of 50 chirps per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 1551 °.B.The slope predicts a temperature increase of about 1551 ° for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 50°.C.The slope predicts a temperature increase of about 50° for every increase of 1 chirp per minute. The y-intercept shows that when the crickets are not chirping (x = 0), the temperature is 0°.D.The chirping increases as the temperature goes down.
