To find the slope and y-intercept of the trend line passing through the point (3.5,9), we first need to determine the slope.

The slope (m) can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)

Given the point (3.5,9) and an arbitrary point (x,y), we can substitute these values into the equation. Let's choose the point (x,y) to be (0, b) where b is the y-intercept we are trying to find:

m = (9 - b) / (3.5 - 0)

Now, since the trend line passes through the point (3.5,9), we have already determined the value of b to be 9.

Therefore, the slope is:
m = (9 - 9) / (3.5 - 0)
m = 0 / 3.5
m = 0

The slope of the trend line passing through the point (3.5,9) is 0.

Now that we know the slope, we can substitute the values into the slope-intercept form of a linear equation: y = mx + b. With m = 0 and b = 9:

y = 0x + 9
y = 9

Therefore, the equation of the trend line passing through the point (3.5,9) is:
y = 9
