the graph is named animal longevity (years)
the y axis is named maximum and ranges from 0-80 the x axis is called average and ranges from 0-45 the trend line goes from (0,20) to (45,72) the points are (8,20) (15,40) (11,49) (20,55) (25,50) (41,62) (39,78) the rise over run is 2/3 what is the slope intercept form of the trend line
To find the slope-intercept form of the trend line, we need to find the slope (m) and the y-intercept (b). The slope can be determined using the rise over run formula, which is the difference in y-coordinates divided by the difference in x-coordinates.
Given points: (0,20) and (45,72)
Rise = 72 - 20 = 52
Run = 45 - 0 = 45
Slope (m) = Rise/Run = 52/45
To convert the slope-intercept form, we need to choose any point on the line. Let's take point (0,20).
Using the slope-intercept form (y = mx + b), we can plug in the values to solve for b:
20 = (52/45)(0) + b
20 = b
Therefore, the slope-intercept form of the trend line is:
y = (52/45)x + 20
