Scott Bell Builders would like to predict the total number of labor hours spent framing a house (Y) based on the square footage of the house (X). The following data have been compiled on 7 houses recently built.

Number of labor hours (Y)	Square footage in 100s (X)
210	25
198	32
228	31
195	36
150	16
206	30
264	42

Calculate the slope. Round up to 4 decimal places and include the 0 before the decimal place AND, OR the MINUS sign when needed. E.g., -0.1234
