Answer: 0
Step-by-step explanation:
To find slope, I found that an easy way is the equation y2 - y1 over (divided by) x2 - x1
so for this, it would be:

which is 0/7
0 divided by 7 is 0, so there is your answer
5/6= c/9
Cross mutiple. 5* 9= 45 . c*6
45= 6c
divide by 6 for 45 and 6c
45/6= 6c/6
45/6= c
Reduce 45/6. Divide by 3
45/3, 6/3
15/2= c
Answer: c= 15/2 or in decimal form , c= 7.5
