1.	If f(x) = ax + b, f(2) = 13 and f(-1) = 1, then find the value of a and b.FAST
Answer» Step-by-step explanation: F(x) = ax + B f(2) = a(2) + b=13 2a+b=13------->I f(-1) = a(-1)+ b, =1 -a+b=1---------->II I-II 3a=12 a=4 from II -4+b=1 b=5 so a=4, b=5

If f(x) = ax + b, f(2) = 13 and f(-1) = 1, then find the value of a and b.FAST

Answer»

Step-by-step explanation:

F(x) = ax + B

f(2) = a(2) + b=13

2a+b=13------->I

f(-1) = a(-1)+ b, =1

-a+b=1---------->II

I-II

3a=12

a=4

from II

-4+b=1

b=5

so a=4, b=5
