A wildlife biologist is interested in the relationship between the number of chirps per minute for crickets (y) and temperature. based on the collected data, the least-squares regression line is y x ˆ = + 10.53 3.41, where x is the number of degrees fahrenheit by which the temperature exceeds 50°. give a sentence that describes the meaning of the slope of the least-squares regression line

Here the slope value means that if the slope value is K. Then for every 1 degree rise in the temperature above 50 degrees Fahrenheit, there would be a K number of chirps per minute increase. Note that in case the slope is negative, the increase in temperature would result in a decrease in the number of chirps per minute.
