Answer:
A( 3, 2)
B( 1, 2)
y=kx+b
3k+b=2
k+b=2
3k-k+b-b=0
2k=0
k=0
b=2
The equation is y=2
Answer: B is correct, y=2
Step-by-step explanation:
The formula for a line is y=mx+b, m is slope, and b is the y-intercept.
The line AB is completely flat, which means the slope is 0, so it won't show up in the equation. So right now we know the equation will be y=b. Now, we mist find b, the y-intercept. The line AB is crossing the y-axis at 2, meaning that's your y-intercept/b! The equation is y=2
