(0,-9);slope=4 (3,-8):slope=-3
(-4,-7);slope=1
(4,9);slope=5
(-6,-8);slope= 5/6
(7,-8); slope= -2

I need each of the problems answered with and explanation.

1. y=4x-9
2. y=-3x+1
3. y=x-3
4. y=5x-11
5. y=5/6x-3
6. y=-2x+6

I’m not sure how to explain this but basically, if you have y=mx+b (the answer), the equation used to find that is y-y1=b(x-x1). b=slope

It’s kind of confusing but I’ll use the first question as an example.

So, y+9=4(x-0) You would substitute in your x, y, and slope and solve it from there. It’s a bit confusing at first but once you understand it’s easy.
