Which of the following numbers is prime? 88,65,51,17

A prime number is one that cannot be divided evenly by anything other than itself and one.
88 is not a prime number because it can be divided by 8, among many other numbers. 65 is not prime because it can be divided by 5, among other factors. 51 is not a prime number because it is divisible by 3, along with other numbers. 17 is not divisible by anything other than itself and one, so... 17 is the prime number.
Hope that helped you.

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
