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

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.

Now we can write our Slope Intercept Equation :)

We have a slope of 8 and a y intercept of 25.

What is the equation of the line?

• (-2,-2)

• (3,3)

• (3,-1)

• (-2,4)

Write the equation of a line with a slope of -3 and y intercept of 8

• x = 8

• y = -3

• y = 8x -3

• y = -3x + 8
