Answer:
[tex]y=1.25x-2[/tex]
Step-by-step explanation:
The function I used was a linear function ([tex]y=mx+b[/tex]). I found the slope and y-intercept by going to my calculator and doing these steps:
1. Turn on the calculator
2. Press the STAT button
3. Select Edit . . .
And the calculator will show an empty data table. If there are already numbers in the data table:
1. Click STAT again
2. Select ClrList
3. Press 2nd and number 1
4. Select the comma, it's above 7
5. Press 2nd and number 2
6. Hit enter
Finally, after entering the numbers into the data table in their according spots, you then:
1. Press STAT
2. Go to CALC and Select LinReg (ax+b)
3. And hit enter 5 times, and you'll get your answer
y = -2
m = 1.25
