# Math Help - Linear Functions Help needed!

1. ## Linear Functions Help needed!

I had this question that seems to be complicated for me..... I m confused coz I cant figure which formula I got to use here..... It would be really good if someone solves this for me..... All help is appreciated!!

The question is :

g is a linear function such that g(-2)=2.8 and g(3)= -5.1
Find a formula for g(x).

2. $g(x)=ax+b$

$2.8=a(-2)+b$

$-5.1=a(3)+b$

solve those two equations... linear functions take the form ax+b, plug in your info and we get those two equations
