Solving systems by graphing

The solution to a system of equations is any ordered pair that makes both equations true. 

• TRUE
• FALSE

How can you tell if a point is a solution to a system?

• It makes the first equation true.
• The (x,y) coordinate values make both equations true.

• It makes logical sense
• It makes neither equation negative

Steffen graphed two lines in order to find the solution to a given system of equations.

If m=3 and b=6, what is the correct slope intercept equation?

• none
• y=3x-6
• y=3x+6
• y=6x+3

What is the solution to this system?

• (-2, -2)
• (2, -2)
• (-2,2)

What are the steps for graphing a line?

• 1. Plot y-intercept
  2. count slope ratio plot second point
  3. Draw the line.
• 1. Make a table
  2. Plot slope
  3. Draw line
• 1. Plot two points
  2. Check slope
  3. Draw line
• 1. Draw line
  2. Hope it is right
