1*3+7*3=3(1+7)=3*8
Hope this helps
Answer: C
Step-by-step explanation:
So you square 5d which is 25d then subtract from 18d equaling 7d then it is simplified to 7d-8
The slope or velocity of a line is constant and is the change in y divided by the change in x.
m=(y2-y1)/(x2-x1) for any two points (x1,y1) and (x2,y2)
m=(-6-5)/(-3--12)
m=-11/9
