Question

The graph shows a plot line of 30 35 and 60 off plot line is 55 and 70 right an equation in slope intercept form of the trend line y equals

Answer 1

To find the equation of the trend line, we first need to calculate the slope of the line using the points (30, 35) and (60, 70).

slope = (70 - 35) / (60 - 30)
slope = 35 / 30
slope = 1.1667

Now that we have the slope, we can use one of the points to find the y-intercept.

Using the point (30, 35):
35 = 1.1667(30) + b
35 = 35 + b
b = 0

Therefore, the equation of the trend line in slope-intercept form is:

y = 1.1667x
