Question
A coordinate plane of quadrant 1 is titled Mass of Gerbil in Grams versus Age in Weeks. An upward sloping line is plotted along with 12 unlabeled plotted points. The x-axis is labeled Age in Weeks and ranges from 0 to 7 in increments of 1. The y-axis is labeled Mass of Gerbil in Grams and ranges from 0 to 300 in increments of 25. A line is drawn startimg at left parenthesis 0 comma 75 right parenthesis and passes through the plotted points left parenthesis 1 comma 100 right parenthesis, and left parenthesis 2 comma 125 right parenthesis shown on the graph. The other points plotted on the graph are as follows, but the line does not go through these points: One point is plotted at the origin. The others are approximately at left parenthesis 2.8 comma 120 right parenthesis, left parenthesis 3 comma 200 right parenthesis, left parenthesis 3.2 comma 170 right parenthesis, left parenthesis 3.7 comma 180 right parenthesis, left parenthesis 4 comma 210 right parenthesis, left parenthesis 4.2 comma 200 right parenthesis, left parenthesis 5.2 comma 195 right parenthesis, left parenthesis 5.4 comma 225 right parenthesis, and left parenthesis 6.2 comma 300 right parenthesis. intercept the data to determine what would be a good approximation of a grebil's mass at exactly 5 weeks old

To determine a good approximation of a gerbil's mass at exactly 5 weeks old, we can use the line that passes through the points (0, 75), (1, 100), and (2, 125).
The slope of this line can be calculated as follows:
slope = (change in y) / (change in x)
= (125 - 75) / (2 - 0)
= 50 / 2 = 25
Therefore, the equation of the line can be written as:
y = mx + b
where m is the slope and b is the y-intercept.
Since the line passes through the point (0, 75), we can substitute the values into the equation to solve for the y-intercept:
75 = 25(0) + b
b = 75
So, the equation of the line is:
y = 25x + 75
To find the approximation of the gerbil's mass at exactly 5 weeks old, we substitute x = 5 into the equation:
y = 25(5) + 75
y = 125 + 75
y = 200
Therefore, a good approximation of a gerbil's mass at exactly 5 weeks old would be 200 grams.
The slope of this line can be calculated as follows:
slope = (change in y) / (change in x)
= (125 - 75) / (2 - 0)
= 50 / 2 = 25
Therefore, the equation of the line can be written as:
y = mx + b
where m is the slope and b is the y-intercept.
Since the line passes through the point (0, 75), we can substitute the values into the equation to solve for the y-intercept:
75 = 25(0) + b
b = 75
So, the equation of the line is:
y = 25x + 75
To find the approximation of the gerbil's mass at exactly 5 weeks old, we substitute x = 5 into the equation:
y = 25(5) + 75
y = 125 + 75
y = 200
Therefore, a good approximation of a gerbil's mass at exactly 5 weeks old would be 200 grams.

I apologize for the mistake. Let's try a different method to estimate the gerbil's mass at 5 weeks old.
One way to estimate the gerbil's mass at 5 weeks old is to find the average mass of the gerbils at week 4 and week 6 and use that as an estimation.
From the plotted points, we can see that the mass at 4 weeks is approximately 210 grams and the mass at 6 weeks is approximately 300 grams.
To find the average mass:
(210 + 300) / 2 = 510 / 2 = 255 grams
So, a good approximation of the gerbil's mass at exactly 5 weeks old would be 255 grams.

I apologize for the error in my previous responses. Let's try a different approach to estimate the gerbil's mass at exactly 5 weeks old.
Looking at the points plotted on the graph, we see that there is an upward sloping line passing through the points (0, 75), (1, 100), and (2, 125), indicating a consistent increase in mass as the gerbil grows older.
When looking at the data points around the 5-week mark, we can see that the mass at 4 weeks is approximately 210 grams and at 6 weeks is approximately 300 grams. Since the line is consistently increasing, and the slope is not changing significantly between these points, it is reasonable to estimate the gerbil's mass at 5 weeks to be somewhere between these values.
A good approximation of the gerbil's mass at exactly 5 weeks old would be the average of the masses at weeks 4 and 6:
(210 grams + 300 grams) / 2 = 255 grams
Therefore, a more accurate estimation of the gerbil's mass at exactly 5 weeks old would be 255 grams. Thank you for your patience.
