2. (-1, 2); m = 7
3. (4, 0); m = -5
m

Answer 1

9514 1404 393

Answer:

1. 2x -y = 13
2. 7x -y = -9
3. 5x +y = 20

Explanation:

For point (h, k) and (integer) slope m, the standard form equation can be written starting with ...

mx -y = mh -k . . . . . m > 0

-mx +y = k -mh . . . . m < 0

So, we have here ...

1. 2x -y = 13 . . . . . 2(5)-(-3) = 13
2. 7x -y = -9 . . . . . 7(-1) -2 = -9
3. 5x +y = 20 . . . . . 0 -(-5)(4) = 20
