Slope Parallel and Perpendicular lines

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

Select the two lines that are perpendicular.

• None are perpendicular.

Slopes of perpendicular lines are...

• opposite (sign) reciprocals.

• opposites.

• identical.

• always 7.

Slopes of parallel lines are...

• opposite reciprocals.
• opposites.
• the same.
• always 7.

Parallel lines have __________ slopes

• Equal
• Opposite
• Reciprocal 
• Total

Which two lines are parallel?

• Line A and Line B

• Line A and Line C

• Line B and Line C

Find the slope of the line that passes through:
(-4, 7) and (-6, -4)

• 2/11
• 13/2
• 3/10
• 11/2

Convert the standard form equation into slope-intercept form.

6x - 7y = -35
