Arabic data analysis and probability unit tests use the image to answer the question write an equation in slope intercept form of the trendline y equals blank it starts at 30 35 and 60 online offline is 55 and 7
To find the equation of the trendline in slope-intercept form, we need to determine the slope (m) and the y-intercept (b) of the line.
First, let's determine the slope (m) using the given points:
(0, 30), (5, 35), and (7, 60)
m = (y2 - y1) / (x2 - x1)
m = (60 - 30) / (7 - 0)
m = 30 / 7
m = 4.2857 (rounded to 4 decimal places)
Next, we can use the slope to find the y-intercept (b) by selecting one of the points (0, 30):
30 = 4.2857(0) + b
30 = b
So, the equation of the trendline in slope-intercept form is:
y = 4.2857x + 30
