Interpreting Linear Graphs and Intercepts and Slope

What is the slope of the equation?

y = -2x - 1

• 2

• -2

• -2x

• -1

Find the slope and y - intercept

• slope: 3 y-intercept: -1

• slope: -1 y-intercept: 3

• slope: 3x y-intercept: 1

• slope: -1 y-intercept: 3x

Find the slope of the line.

Hint: rise/run

• 1/2

• -1/2

• 2

• 0

What is the y-intercept in the equation

y= -2x

• -2

• -2x

• 0

• 1

How many solutions?

• One Solution

• No solution

• Infinitely Many Solutions

What is the number of solutions to the system of equations?

• No Solution

• Infinitely Many Solutions

• One Solution

• Two Solutions

How many solutions will this system have?

• One

• Two

• No Solution

• Infinitely Many Solutions

If a system of linear equations has one solution, what does this mean about the two lines?

• Parallel lines

• the same line

• Intersecting lines

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. 

• 1 solution

• 2 Solutions

• No Solution

• Infinite Solutions
