Question

Write a linear function rule for the data in the table

Answer 1

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.
