help with math please?

Question

1. Solve the following system of equations using any method:
3x - 2y = 22
2x + y = 10

A. (5,0)
B. (10,4)
C. (6,-2)
D. (10,-10)

2. This equation, 6x - 3y = -12, crosses the y axis at ______.

3. Which of the following is NOT true about intersecting lines?

A. Intersecting lines have one solution.
B. Intersecting lines are consistent
C. Intersecting lines are independent
D. Intersecting lines have the same slope

4. Solve the following system of equations using any method:
y = -3x + 4
x + 3y = 12

A. (-2,10)
B. (-4,0)
C. (0,4)
D. (-6,6)

5. Perpendicular lines form a right angle at the point of intersection? Yes or No

6. ___________ lines form a 90-degree angle where they intersect.

7. Which TWO linear equations represent perpendicular lines?

A. y = ½x + 4
B. x - 3y = -8
C. y = -2x - 3
D. y = 2x - 4

8. Fill in the missing # for the solution to this system of equations:

2x + 4y = 8
3x + 2y = 10

x = ____?

9. This equation, 8x - 2y = -16, has a slope of _____?

Answer 1

1.c try some of the given answers and c works.
2. crosses y axis is math mumbo jumbo for x=0
plug in x=0 to get y=4. crosses x axis is also code for y=0.
3. D
4. C
5. Perpendicular is code for 90 deg so YES
6. Perpendicular
7. A & C slope of A (1/2) is the negative reciprocal of the other -2
8. x=3
9. 4

Answer 2

This looks like half of a test or something. If its a placement test for school then don't answer the ones you don't know just try your best if you answer everything right because some else told you, your gonna be placed in a higher math class than you should be in.

no ones gonna answer them for you either way
