Which of the following lines goes through the point (-3, 4) and is perpendicular to y = 3/2x + 6?

• y - 4 = 3/2(x + 3)

• y - 4 = 2/3(x + 3)

• y + 3 = -2/3(x - 4)

• y - 4 = -2/3(x + 3)

Given the line 2x-3y=9, write the equation of a line parallel to it that passes through the point (4, -1)

• y + 1 = -3/2(x - 4)

• y + 1 = 2/3 (x - 4)

• y - 4 = -3/2(x + 1)

• y - 1 = 2/3(x + 4)

The slope of one line is -1/2. The slope of another line is 1/2.

Are these lines...

• parallel

• perpendicular

• neither
