Answer 5

yes i am sure

Answer 6

that is the equation of the tangent line, tangent line and gradients arent the same though

Answer 7

Answer 8

when i use your method on that gradient it gives me the right answer?

Answer 9

ok cool, its just that we use gradient word for something else in my math class
