Mark Brainlies please!

y=0.126x-7.124 2025, x=125

y= (0.126)•125-7.124

y= 15.75 - 7.124

y= 8.626

y=$8.63

Step-by-step explanation:

Enter STAT on TI 83 or 84 graphing calculator. GO to 1 : Edit push enter. L1 enter all the years and L2 enter all minimum wages. Then push STAT AND MOVE RIGHT TO CALC ON TOP OK. SCROLL DOWN TO 4: LinReg ( ax+b) push enter. Push enter till it calculates. Then look at a=.1258733205 and round to the nearest thousandths which gives you 0.126 ok. This is the least square regression. y=0.126x-? . Ok then take the last wage which is 7.25 and subtract 0.126. Which gives you 7.124. y=0.126x-7.124. Then you need to figure out time time from 1900 to 2025. Take 2025 subtract from 1900 and gives you x= 125 years past 1900. Then take y= (0.126)•125-7.124

y= 15.75 - 7.124

y=8.626 round to the nearest hundredth y=$8.63. Hope this helps. Y’all have a great weekend.
