Algebra 7.1 w/o graphing

Analyze the slope and y-intercept and then decide how many solutions are there in the following systems of equations.
y = 3x -4
y= 6/2 x -4

• One Solution
• No Solution
• Two Solutions
• Infinite or Many Solutions

Analyze the slope and y-intercept and then decide how many solutions are there in the following systems of equations.
5x + y = 4
6x - y = 3

• One Solution
• No Solution
• Two Solutions
• Infinite or Many Solutions

Analyze the slope and y-intercept and then decide how many solutions are there in the following systems of equations.
y= 5x - 12
y = 4x - 3

• One Solution
• No Solution
• Two Solutions
• Infinite or Many Solutions

Analyze the slope and y-intercept and then decide how many solutions are there in the following systems of equations.
y = 12/4x + 3
y= 9/3x - 3

• One Solution
• No Solution
• Two Solutions
• Infinite or Many Solutions

Analyze the slope and y-intercept and then decide how many solutions are there in the following systems of equations.
-15x - y = -12
30/2x + y = 36/3

• One Solution
• No Solution
• Two Solutions
• Infinite or Many Solutions

Analyze the slope and y-intercept and then decide how many solutions are there in the following systems of equations.
8x + 4y = 12
y = -2x + 3

• one solution
• same slope
• No solution(parallel lines)
• Infinitely many solutions

Parallel Lines never intersect because...

• they have the same slopes and different y-int. 
• they have the same slope and same y-intercept.
• they have different slopes.
• they have different y-intercepts. 

How many solutions?

• One Solution
• No solution
• Infinitely Many Solutions

What is the solution?

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