Equations of Parallel and Perpendicular Lines Homework
A. Determine whether the lines are parallel, perpendicular, or neither given the
equations.
1) y = -2x + 5;
y = 2x – 3

D. Find the standard equation of a line through the given point A that satisfies the
given condition. Graph the lines.
11) Point A (2,1)
a. parallel to the y-axis
b. perpendicular to the y-axis
12) Point A(2,-4); parallel to the line 5x – 2y = 4.
13) Point A(4,5); perpendicular to the line 3x + 2y = 7
