Which of the ordered pairs (6, 1), (10, 0), (6, –1), (–22, 8) are solutions for the equation x + 4y = 10?

Question:Having trouble with these problems.
1. Which of the ordered pairs (6, 1), (10, 0), (6, –1), (–22, 8) are solutions for the equation x + 4y = 10?
2.Complete the ordered pairs for the equation y = 3x + 9.
( ,0) , (1/3 , ) , (0, ) , (-1/3, )
3. Plot the point with coordinates (0, 2). You can describe the graph instead of actually making it.
4. Graph 3x + 2y = 6. What would it look like?
5. Find the slope of the line passing through the points (–4, 3) and (10, 3).
6. Find the slope and y-intercept. 2x – 5y = –45
7.Find the slope of any line parallel to the line through points (19, 1) and (10, 2).
8. Write the equation of the line that passes through point (0, –5) with a slope of 1/8 .
9. Write the equation of the line that passes through point (0, 7) with a slope of –8

Answers:
1. (6,1) (10,0) (-22,8) are all valid solutions. All you have to do is put the first number of an ordered pair into the X place, and the second # into the Y place, then work through to see if both sides are equal.

2. (-3,0) (1/3,10) (0,9) (-1/3,8)

3. North two squares.

4. Change to y = mx + b and go from there.

5. m = 0

6. m = 2/5; I forget the y-intercept thing

7. Parallel lines have the same slope, m = -1/9

8. put values of x and y into "y = mx + b" and solve for b; y = 1/8x -5

9. Same idea; y = -8x + 7

PS problems 8 and 9 are perpendicular lines!!
I always hated math.
1. the first, the second and the fourth
3. like \
1. (6,1)
3. Make a graph and when you put the point, go up two and put a dot.
5. -1

Here, since I did three for you, can you tell me if this is Algebra 1, Algebra 2? What?
1. all except (6, -1)
2. (-3,0), (1/3,10), (0,9), (-1/3,8)
3. you do that
4. when x=0, y=3, when y=0, x=2 when x=1, y=1.5 draw a line between them
slopes - I forget
1. (10,0) (6, 1) (–22, 8)
2. (3,0) (1/3,10) (0,9) (-1/3,8)
3. it's on the absyss line
4. it looks like a line
