Question

Write the slope intercept equation for line AB.

Answer 1

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 2

Answer: B is correct, y=2

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
