nope, he's right. x value was 10, y was 13. Those numbers don't compute in what you gave.


I agree with every single one of the OP's answers.

Gradient was -1/(5/3)

y - 13 = -3/5(x - 10)

5y - 65 = -3(x - 10)

3x + 5y - 95 = 0

it was definitely +5 as it was y-13= -3/5(x-10)
so
5y-13=-3x+10

Guys wasn't part a of Q9 = 1/3pi(x^2)????

because the sector area is 1/2r^2(theta)
which is 1/2(x^2)(2/3pi)

= 2/6pi(x^2)
= 1/3pi(x^2)
??
