The top question is y=2x+6
the bottom question is y=5/2x-6
Cot theta is 1 over tan theta.The only way for 1/tan theta to be undefined is for tan theta = 0. - answers
So the first 10 are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Since a prime number is only divisible by 1 and itself and greater than 1, our answers are 2, 3, 5, and 7. That's 4 numbers, or 4/10=0.4 of the 10. Since percentage is based out of 1, we can multiply 0.4 by 100 to get 40%. I hope that Helped :)
