Question

Please I need help...

9. Find a linear function F(x)=ax+b for which f(2)=1 and f(-3)=11

Answer 1

We are given f(2)=1 and f(-3)=11
So, let's consider f(2)=1, which means when you replace x by 2, you'll get 1 from the function. So, replacing x by 2, we get
f(2) = a(2) + b
And we know f(2) =1. Hence, we get
1 = a(2) + b

Can you use similar logic to get another equation in terms of a and b by f(-3)=11?
