Question

rob is investigating the effects of font size on the number of words that fit on a page. he changes the font size on an essay and records the number of words on one page of the essay. the table shows his data.
words per page

font size14121610121416182422
word count352461340407435381280201138114

which equation represents the approximate line of best fit for data, where x represents font size and y represents the number of words on one page?
o y = -55x + 407
o y = -41x + 814
o y = -38x + 922
o y = -26x + 723

Explanation:

Step1: Identificar variables

x: Tamaño de fuente, y: Número de palabras

Step2: Usar una calculadora de regresión lineal

Insertar los valores de x (tamaño de fuente) e y (conteo de palabras) en una calculadora o software de regresión lineal.

Step3: Obtener la ecuación

La ecuación de la recta de mejor ajuste obtenida es y = - 41x + 814.

Answer:

y = - 41x + 814
