Can slope be written as a whole number instead of a fraction?

Yes, slope can be written as a whole number instead of a fraction if the slope is a whole number. In slope-intercept form (y = mx + b), the slope (m) represents the rate of change between two variables. If the slope is a whole number, it can be written as a whole number without the need for a fraction. For example, a slope of 3 would be written as "3" rather than "3/1."
