And
How many real-number solutions does the equation have?
-8x^2-8x-2=0
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
1+4x+4x^2=0
(1+2x)^2=0
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
