Answer is b. F(x)=-2x+3
Because y=mx+b
B is y when x is at zero in this case 3
M is the amount it’s increasing or decreasing in this case it’s -2
F(x) represents y so when you plug a number in for x it will give you the y value once you solve equation
We know this because 1-2=-1 and -1-2=-3 and -3-2=-5 they all decrease by 2 which is your m
