|dw:1345323672460:dw|

phi · Answer

for the equations, the slope is m in
y= mx+b
in other words the slope m is the number multiplying x.  the y-intercept is just b

anonymous · Answer

$$y=mx+b$$

phi · Answer

For the graph,  look at the line
where does it cross the vertical line (y-axis) that is the y-intercept

phi · Answer

positive slope is goes up as you go to the right
negative slope goes down as you go to the right

anonymous · Answer

you can find the slope (m) by plugging in:
|dw:1345323865893:dw|
