-43
Answer:
B
Step-by-step explanation:
well plug in x and y
so if it says y=2x-3 put it as 7=(2x2)-3 and see if it gives u 7 and if it does di the next set of x and y numbers
F(x) = ax + b
maka..
f(1) = 3
a(1) + b = 3 --> a+b = 3
f(2) = 5
a(2) + b = 5 --> 2a+b = 5
untuk mencari nilai a dan b nya, di eliminasi, maka dapat
a=2 dan b=1
