Question

(06.02 LC) Line AB contains points A (0, 1) and B (1, 5). The slope of line AB is (5 points) Group of answer choices −4 negative 1 over 4 1 over 4 4

Answer 1

The correct answer for this question would be D

Answer 2

General equation of line is
`y=mx+n` where m is slope and n is point on y-axis. So just use points in question to determine what m and n must be. Let me show you.

For A(0,1), put this point in
`y=mx+n` then you have
`1=m.0+n` Hence
`n=1`

Now use second one that is B(1,5), then you get
`5=m.1+1` since
`n=1`. Finally you get
`m=4` that is slope.

Therefore, D is the correct answer.
