Solving Systems by Graphing

What is the solution?

• (1, -1)
• (-1, 1)
• (0, -2)
• (2, 0)

Lesly graphed two lines in order to find the solution to a given system of equations.
What is the solution?

• (-3,-8)
• (-8,-3)
• (3,-8)
• (8,3)

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. 

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. 

How many solutions will this system have?

• One
• Two
• No Solution
• Infinitely Many Solutions

How many solutions will this system have?

• No Solution
• Infinitely Many Solutions
• No Clue
• One solution

What is the solution to a system of equations?

• The point that the equations have in common.
• The point where the two lines intersect. 
• All of the above. 

What is the first step in solving a system by graphing?

• Write both linear equations in slope-intercept form
• Get x by itself
• Compare the slopes of both equations
• Write both equations in standard form

What is the
slope-intercept form
of the equation
-8x+2y=4

• none
• y=2-4x
• y=4x+2
• y=4x-8y

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

• none
• y=3x-6
• y=3x+6
• y=6x+3
