Answer:
number 5:4/12
#6: 25/45
#7: 26/44
#8: 52/30
Step-by-step explanation:
I believe its the first one, think of it like a mirror you would flip the shape which would do make x negative and y positive, sorry if im wrong
The two points are (1,30) and (7,55). Slope = the change in y/the change in x. Slope is -25/-6, which simplifies to 4.2.
The answer is b. 34.
Each term increases by 11.
