Answer 5

rise over run, so you get change in y over change in x.

Answer 6

I don't know what y is?

Answer 7

plug the x values into your function, then subtract the second one from the first then divide that by 7-4....

Answer 8

isn't 4x^2+16x+13 your function?

Answer 9

like f(x)=4x^2+16x+13?

cause if you aren't given your function you can't find the answer for that.....

Answer 10

yah

Answer 11

so basically sub 4 and 7 into the x values for that function, then subtract the value you got for 4 from the value you got for 7, and then divide that by 3
