The red and the blue triangles drawn on the line are similar. what equation can be used to show that the slope of the line is the same between any two points? a. rise 1 x run 1 = rise 2 x run 2 b. rise 1 + run 1 = rise 2 + run 2 c. rise 1/run 1 = rise 2/run 2 d. run 1/ rise1 = run2/rise2

The formula for finding the slope of a line is y= rise/run.

Using this information, we can plug in the numbers given on the image.

The slope of the blue triangle would be 2(rise)/2(run), which simplifies to 1/1=1.

The slope of the red triangle would be 1(rise)/1(run), which simplifies to 1/1=1.

Seeing as the slopes are equal, the answer choice is C.
