Answer
Using the given computer data output
Intercept
and slope
Rounding to two decimals, we get
Intercept = 24.04 (it is value of dependent variable when independent variable is 0)
and slope = 4.89 (it is showing that for every unit increase in independent variable, there is 4.89 unit increase in dependent variable)
