9. Graph the following two lines on the graph below: A. y + 3 = 2 (x – 4)
B. y – 1 = – (x + 3)
*Hint, find slope and a point
(Remember, points come out with opposite signs.)
10. Are the following lines, parallel, perpendicular, or neither?
A. x = 2
B. y = 7x
y = –5
y – 28 = 7(x – 4)
11. Write an equation in slope-intercept form
for the line that passes through (0, 6) and
is parallel to y = 2x + 3.
C. 2x – y = 1
x – 2y = –4
D. y = 6x – 2
x + 6y = –48
