The answer would be B. Heptagon.
The equation 2 has a graph which is a straight line.
Why?
We can know which of the given equations has a graph which is a straight line just checking the exponents of the variables.
We must remember that every variable that has an exponent equal or higher than 2 (quadratic) will not have a straight line as a graphic.
So, checking the exponents from the given equations, we have:

Hence, we can see that the only equation that has a linear term (straight line graph), is the second equation.
Have a nice day!

Answer:
x≥-6
Step-by-step explanation:
The domain is every value of x. Since the function does not include any values of x less than -6, x≥-6 is the domain.
Answer:
x=0, 1/4
Step-by-step explanation:
16x^2-4x=0
factor out the 4x,
4x(4x-1)=0
zero property,
4x=0, 4x-1=0,
x=0/4=0
4x=0+1
4x=1
x=1/4
