You are using a trend line the y axis begins on 9 with a points on (3.5,9) write an equation in slope intercept form of the trend line

Answer 1

To find the equation of the trend line in slope-intercept form (y = mx + b), we first need to determine the slope (m) of the line.

We are given the points (3.5, 9) on the trend line. This means that 3.5 is the x-coordinate and 9 is the y-coordinate.

To find the slope (m), we can use the formula:
m = (y2 - y1) / (x2 - x1)

Substitute the coordinates into the formula:
m = (9 - 9) / (3.5 - 0)
m = 0 / 3.5
m = 0

Since the slope is 0, the equation of the trend line is a horizontal line.

A horizontal line through the point (3.5, 9) with a y-intercept of 9 would have an equation:
y = 9
