Writing parallel and perpendicular Lines

 Identify the slope-intercept equation:

• y = 2x - 2
• y = -2x + 2
• y = -2x + 4
• y = 2x + 4

Write the equation of the line with slope -2 through the point (7, −1).

• y = −2x + 15

• y = −2x − 15

• y = −2x + 13

• y = −2x − 13

What is the equation of this line?

• 0
• undefined 
• y = -2
• x = -2

A line that is parallel to this line would have what slope?
y= 2x - 7

• 2
• 1/2
• -1/2
• 7
