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
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.
Nope no typo on the third it is 20. Thanks Bob
Sorry it is 1,5
