    Step-by-step explanation:

    The slope in the linear regression line shows the increase in dependent variable y due to unit change in independent variable x.

    The given LSRL (least square regression line) is

    y^=3x+5

    Here, 3 represents the slope of line and 5 represents intercept of the line.

    So, the increase of 1 unit in x is associated with an increase of 3 units in y.
