Answer:
B. y= -2x+3
Step-by-step explanation:
1) the slope-interception form is: y=s*x+i, where s - slope, i - interception are unknown numbers;
2) if y(0)=3, then i=3, it means the equation is y=s*x+3;
3) if to substitute x=1; y=1 into the equation y=s*x+3, then s= -2. It means, the initial equation is y= -2x+3.
4) finally, the correct answer is B.
