I have a couple questions I need help on.
Which model is most appropriate for the data set?


How many real-number solutions does the equation have?
Thanks for the help

  • algebra -

    on the first sets, each increase in x results in y being increased by 5 (assuming you have a typo in the third set, and it should read (1,15). So linear.

    divide by 2


    x= -1/2, -1/2 so one real solution.
