use similar triangles to determine the slope of the line. write your answer in fraction form.

(0,0), (2,1), (4,2), (6,3), (8,4)

the slope is _

Answer 1

To determine the slope using similar triangles, we can compare the change in the y-coordinate to the change in the x-coordinate.

Starting with point (0,0), we can see that as x increases by 2 units, y increases by 1 unit.

So, the slope between (0,0) and (2,1) is:
Change in y / Change in x = 1/2.

We can observe the same pattern for the other points:
(2,1) and (4,2) have a slope of 1/2,
(4,2) and (6,3) have a slope of 1/2,
(6,3) and (8,4) have a slope of 1/2.

Therefore, the slope of the line connecting these points is 1/2.
