2. (4, -2)
Answer: P

3. (-3, -2)
Answer: S

4. (2, 1)
Answer: J

Remember, to find the coordinates of something, start from the origin, then go right (if the number is positive) or left (if the number is negative) along the x-axis, then up (if the number is positive) or down (if the number is negative) for the second number. 

Part B
 
A) Coordinates: (4, 2)
B) Coordinates: (1, -1)
C) Coordinates: (1, 4)
D) Coordinates: (-2, 2)

A) going left to right from top to bottom
1.M
2.P
3.S
4.J

Explanation: the points for ex. (-1, -1) tell you how far you're going left or right and up or down. In this one the first number -1 means you're going 1 unit left 
and the the second one means you're going down 1 unit.

Solve the equation -9x+1=-x+17​
Step2247 [10]

Answer:

x=-2

Step-by-step explanation:

-9x+1=-x+17

Add 9x on both sides:

     1=8x+17

Subtract 17 on both sides:

   -16=8x

Divide both sides by 8:

     -2=x

Check x=-2!

-9x+1=-x+17     with x=-2

-9(-2)+1=-(-2)+17

18+1=2+17

19=19

19=19 is a true equation so x=-2 is correct.

Find the equation of the plane that goes through three points:
frosja888 [35]

The equation of the plane that goes through these points is:

6x + 2y + z = 10.

<h3>How to find the equation of a plane given three points?</h3>

The equation of the plane is found replacing the points into the following equation:

ax + by + c = z.

For point A, we have that:

3b + c = 4.

For point B, we have that:

a + 2b + c = 0.

For point C, we have that:

-a + 6b + c = 4.

Hence the system is:

  • 3b + c = 4.
  • a + 2b + c = 0.
  • -a + 6b + c = 4.

From the first equation, we have that:

c = 4 - 3b.

Replacing in the second, we have that:

a + 2b + 4 - 3b = 0

a - b = -4.

Replacing in the third, we have that:

-a + 6b + 4 - 3b = 4.

-a + 3b = 0.

a = 3b.

We have that a - b = -4, hence:

3b - b = -4

2b = -4

b = -2.

a = 3b, hence a = -6.

c = 4 - 3b -> c = 10.

Hence the equation is:

ax + by + c = z.

z = -6x - 2y + 10

6x + 2y + z = 10.
