the dots are (-6,1), (0,0), (6,-1)

Find the slope of the line using similar triangles.
The slope is __.

1 answer

-1/6

To find the slope using similar triangles, we can use the formula:
Slope = (change in y) / (change in x)

First, let's find the change in y:
change in y = final y - initial y
change in y = -1 - 1
change in y = -2

Next, let's find the change in x:
change in x = final x - initial x
change in x = 6 - (-6)
change in x = 12

Now, we can calculate the slope:
Slope = change in y / change in x
Slope = -2 / 12
Slope = -1/6

Therefore, the slope of the line using similar triangles is -1/6.
