Answer:

  the graph is reflected vertically across the horizontal line y=7

Step-by-step explanation:

The change of sign of the slope means the graph will go up 5 units for each unit of run, instead of down 5 units. Essentially, the graph of the changed function is the mirror image of the original across the horizontal line through the common point (the y-intercept).

This is shown in the attachment.
