Yes, the equation y = 5 is indeed in slope-intercept form. The slope-intercept form of a linear equation is typically written as y = mx + b, where m represents the slope of the line and b represents the y-intercept.
In the case of y = 5, we can see that this is a horizontal line. The slope (m) is 0 because there is no x-variable present. This means that no matter the value of x, the value of y will always be 5. The y-intercept (b) is 5, indicating that the line crosses the y-axis at the point (0, 5).
Thus, although it may look simple, y = 5 fits perfectly within the slope-intercept framework, representing a horizontal line where all points share the same y-value.
