Slopes of Lines with Graphs

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. 

What is the solution?

• No solution

• (0, 2)

• (0, -4)

• (3, -3)

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

• Parallel lines

• the same line

• Intersecting lines

The steepness of a line is called a

• slope

• y-intercept

• x-intercept

• slope-intercept

Find the slope of the line.

• -5/4

• 5/4

• -4/5

• 4/5

find the slope

Match the following slopes:

• Opposite Reciprocals

• Linear Parent Function

• Undefined

• Horizontal Line

• Equal

• Parallel Lines

• 0

• Perpendicular Lines

• 1

• Vertical Line

If the line goes UP from left to right, the slope is ​ (a)   .

If the line goes​ (b)   from left to right, the slope is negative.

If the line is vertical (straight up and down), the slope is ​ (c)   . If the line is ​ (d)   , the slope is ​ (e)   .

• positive

• down

• undefined

• horizontal

• zero

A horizontal line has the slope of zero.

• True

• False

Match the Graph with its slope.

• Positive

• 
• Negative

• 
• Zero

• 
• Undefined
