Linear Equations and Slope

What is the definition of slope?

• How steep a line is. 
• The change in the x value over the change in the y value
• The change in the y value over the change in the x value
• A positive or negative line

What is the slope of a vertical line?

• Vertical 
• Horizontal
• undefined
• zero

What is the slope of the line passing through the points (0,0) and (-5, -5)?

• 1
• 1x
• -5
• -1

What is the slope of the line that passes through the points (2, 6) and (-3, -5)?

• 5/11
• -1
• 11/5
• -11/5

The slope of a horizontal line is 

• 0
• undefined
• really really cool!!!!
• positive

Slope intercept form is written as:

• y = x
• y = mx + b
• y-y₁ = m(x - x₁)
• y₂-y₁/x₂-x₁

Write the equation of the line that passes through (-2 , 8) and (-2 , 9)

• x = -2
• y = -1/4x + 3
• y = -2

The slope of this line is 

• positive
• undefined
• zero
• negative

A line has an equation y-5 = 4(x + 2). Name one point on this line.

• (-2,5)

• (-5 , 2)

• (5 , -2)

• (5 , 2)

What is the equation in slope intercept form of the line containing the point (0,0)?

• y = 0
• x = 0
• More information is needed. 
• y = x
