Question

The figure below shows a line graph and two shaded triangles that are similar:

Which statement about the slope of the line is true?

The slope from point O to point A is fraction 1 over 4 times the slope of the line from point A to point B.
The slope from point O to point A is four times the slope of the line from point A to point B.
It is fraction negative 1 over 4 throughout the line.
It is −4 throughout the line.

Answer 1

Both triangles are along the slope of the line, so the slope for both triangles are the same.

Using two points on the slope you find that the slope is -1/4

The answer is:

It is fraction negative 1 over 4 throughout the line.
