Slopes and Graphing Lines

Parallel Lines never intersect because...

• they have the same slopes. 

• they have the same y-intercept.

• they have different slopes.

• they have different y-intercepts.

What are the steps for graphing a line?

• Plot y-intercept
  count slope ratio plot second point
  Draw the line.

• Make a table
  Plot slope
  Draw line

• Plot two points
  Check slope
  Draw line

• Draw line
  Hope it is right

• y= -1x-3
• y= -3x-1
• y=(-1/3)x-1
• y= -3x-3

The solution is:

• (4, 3)

• (3, 4)

• (-4, 3)

• No solution
