1. True or False:

The ordered pair (-4, 5) is a solution of the following system of equations:
3X - 4Y= -32
-7X + 10Y = 78

2. Which one is addition method and which one is substitution method?
(20x -3y = 14) and (4x + 10y = -8)
or
(x = 3y + 14) and (4x + 10y = -8)

3. What is the slope of the line passing (5,0) (9,40).

4. Which one is: Parallel, Perpendicular, or neither.
x = -3y + 4
y = -3x -3
y= 3x + 2

5. Solve the system by any method.
x= 7/4 y + 3
4x - 7y =12

6. What is the slope of the line passing through the points (5,2) and (0,0).

7. Determine whether the graphs of the pair of equations are parallel, perpendicular or neither.
