The graph shows the line of best fit for the data.The equation of the line of best fit is given below.Which of the following statements is true? A) The slope of the line is 31.82, meaning that Hannah initially put $31.82 into her trip account. B) The y-intercept of the line is 31.82, meaning that on average, Hannah saved $31.82 each month.C) The y-intercept of the line is 92.73, meaning that Hannah needed $92.73 to go on her trip. D) The slope of the line is 92.73, meaning that on average, Hannah saved $92.73 each month.
Accepted Solution
A:
D) is correct.
Looking at the graph, it goes through the point (2, 200) and is very near the point (3, 300). This means it increases by nearly 100 every month; this tells us how much she saves each month.
