I'LL MARK BRAINLIEST IF YOU SHOW YOUR WORK 1. The following table shows the minimum wage rates for the United States during different years.

Year: 1978 1979 1980 1990 1991 1996 1997 2007 2008 2009

Minimum hourly wage ($): 2.65 2.90 3.35 3.80 4.25 4.75 5.15 5.85 6.55 7.25

(a) Write the least squares regression equation that models the data. Let x equal time in years since 1900 and let y equal minimum hourly wage.

(b) Use the equation to estimate the minimum hourly wage of a US worker in 2025. SHOW YOUR WORK FOR EACH STEP! PLZZ
