Answer:
B
Step-by-step explanation:
I had this on my previous test, lol
The slope is -4.7 because this equation is written in point slope form. This equation can be rewritten as y = -4.7x + 21. Point slope form is y = mx + b, with m being slope and b being y-intercept.
The radius would be 10 and the arc would be 5.
I hope this helps.
Have a blessed day!
