CPM Algebra Chapter 6

Parallel Lines have the _____ slope

• opposite reciprocal

• same

Write an equation for a line parallel to the line
y = 1/3x - 4 through (-3, 2)

• y = 2/3x +3

• y = 1/3x + 1

• y = 1/3x + 3

• y = -5/3x + 1

Write the equation of a line PARALLEL to y = 2x + 3 that passes through the point (3, 1).

Write an equation for the line parallel to y = 4x that passes through (1, 0).

• y = 4x + 4

• y = 4x - 4

• y = 4x + 1

• y = 4x - 1

Use (1997, 13) and (2005, 22) to find the slope.
