Question

Write an equation for a linear function f that has the given value: f(-2)=-2, f(4)=-8

Answer 1

y=-x-4. shall i simplify??

Answer 2

yes

Answer 3

f(x)=mx+n
f(-2)=-2m+n=-2
f(4)=4m+n=-8
(4m+n)-(-2m+n)=-8-(-2)
4m+n+2m-n=-6
6m=-6
m=-1
4m+n=-8
4*(-1)+n=-8
-4+n=-8
n=-4
f(x)=-x-4
did you get it??

Answer 4

oh its simple lol. Thank you.

Answer 5

you're welcome :)
