Slope Intersect

Determine the equation of a line perpendicular to y=-3x-2 and going through the point (9, 2), in slope-intercept form.

Write an equation that is parallel to 
y = -2x + 4
and runs through the point (-3, 2 )

• y = - 2x - 4

• y = - 2x - 8

• y = - 2x + 4

Slopes of perpendicular lines are...

• opposite reciprocals

• opposites

• identical

• reciprocals

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. 

Lisa and Tammy are selling items at the craft show.  Which might be a reasonable solution from the graph showing the number of items sold when they both have earned the same amount?

• (3, 19)

• (5, 25)

• (0, 10)

When you graph the exact same equation twice,

• you will have no solution. 

• you will have one solution.

• you will have infinite solutions. 

• you will graph a giraffe.
