Answer:
the answer is B
f(x)=-2x+3
Explanation:
to get the -2x I did --->
pick two points I used (0,3) and (1,1) and used the equation

where y2 would be 1 and y1 would be 3
and where x2 would be 1 and x1 would be 0
so you would put the numbers in the equation which would look like
and equal -2 which would be -2x in the answer
And the +3 is the y-intercept
