Answer

Slope of the line is coefficient of x, which is 0.918 and intercept is the value of y, which is 0.2. Hence with increase of value of x by .918, value of y increases by 0.2. From the given data we observe that minimum value of x is -1 and maximum value is 7. Hence, this interpretation is valid for values of x from -1 to 7.
