Answer: 6
Step-by-step explanation:
The constant is a number that doesn't change at all. 8x² is not a constant because this number increases every time you plug in an x. -7x is also not a constant because this number decreases every time you plug in x.
We also know 6 is a constant because it is the y-intercept. No matter what, the y-intercept does not change. Therefore, 6 is the constant.
