B. y - 3 = ½ (x + 4)
7. Write the linear equation that passes through (4, 3) and (3, 9). Show work for slope.
8. Plot the ordered pairs and label: ( 2, -3), (-4, 5) and (0, 6).
9. Write the linear equation that passes through (3, 5) and (7, 8).
10. W
rite the equation of the line parallel to 2x – 3y = 5 and passes through the point (4,-3). For three
bonus points, find the equation of the line perpendicular to 2x – 3y = 5 that passes through (4,-3).
Bonus: (3 pts) If x + y = 5 and x - y = 1, what is the value of
2
x^2 – y^2
?
(3 pts) If 2010x + 2010y = 2011(x + y), what is the value of x/y?
