Final answer:
No, h(x) = 23 is not a linear equation because it does not have any variables or coefficients to represent a slope or y-intercept.
Step-by-step explanation:
No, h(x) = 23 is not a linear equation. It does not have any variables, which means there is no independent variable x or any slope or y-intercept.
A linear equation typically follows the form y = mx + b, where m is the slope and b is the y-intercept. In the given equation, h(x) = 23, there are no variables or coefficients, so it does not have a slope or y-intercept.
