Which polynomial is prime?

x2 – 36

x2 + 16

x2 – 7x + 12

x2 – x – 20

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.

thats not a system of equations, that is a solution
