Answer:
First one is 25/2
Step-by-step explanation:
12×2+1=25/2
9×4+1=36/4
cross multiply and you get
100/
divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore
Answer:
y=1/2x+5/2
Step-by-step explanation:
4-3=1
3-1=2
m=1/2x
So now you have y=1/2x
Insert into equation
y=1/2x+?
Now sub you slope in to last points, and you get 5/2
So now you final answer is:
y=1/2x+5/2
Answer:
y = 2x -5
