Answer:
B. f(x) = 0.9x + 1.1
Step-by-step explanation:
First, get the slope from using two pairs of points
y2-y1 / x2 - x1
3-2/ 2-1
1/1
1
Then, get the y-intercept
y=mx + b
2=1(1) + b
2 = 1 + b
b = 1
The equation is about:
y=x+1
You're trying to find the best one, so find the closest one
B is the closest
