Question

The graphs below shows a change in the slope of the Line m from 34to 14.

Which statement is true for the value of y when x has a value of 12?

The value of y increased from 1 to 3.

The value of y decreased from 3 to 1.

The value of y increased from 3 to 9.

The value of y decreased from 9 to 3.

Answer 1

Look at the image attached to my answer.

When x is 12 for the first graph, we see that y is roughly 9. When x is 12 for the second graph, we see that y is roughly 3.

Thus, the value of y decreased from 9 to 3 after the change was applied to line M.

Let me know if you need any clarifications, thanks!
