how to graph slopes(m) and the y-intercepts(b)? (y=mx+b)

1) A good first step would be to solve for "y=". Then read off the slope m and the y-intercept (0, b). For the graphing, just plug in x-values, chug away to find the y-values, draw the dots, and connect them to guide the drawing of the line.

2) This one works just like (1).

3) This is already solved for "y=", so just follow the rest of the instructions, if you don't remember what they said about horizontal lines.

4) This one works just like (1).

If you get stuck, please reply showing how far you have gotten. Thank you.
