Answer:

1x+1

Step-by-step explanation:

Add all the numbers together with an x attached to it so 2x+3x=5x+-4x=1x

Then do the same with any other numbers but in this case there is only a 1

Answer:

1) Variables = 11a , 4a

Constants = 0

Coefficients = 11 , 4

2) Variables = 3x , 7x

Constants = 6 , -4

Coefficients = 3 , 7 , 6 , -4

3) Variables = -12m , +4m

Constants = -3 , 16

Coefficients = -12 , 4 , -3 , 16

4) Variables = 6k , k

Constants = -4 , -2

Coefficients = 6 , 1 , -4 , -2

5) Variables = -5p , -2p

Constants = 3 , 13

Coefficients = -5 , -2 , 3 , 13

6) Variables = -10r , -r , -6r

Constants = 11

Coefficients = -10 , -1 , -6 , 11

7) Variables = -5n

Constants = 19 , -8 , 14

Coefficients = -5 , 19 , -8 , 14

8) Variables = 13y , -2y

Constants = 18 , -5

Coefficients = 13 , -2 , 18 , -5

9) Variables = 8a , 3a , -7b , -2b

Constants = 1

Coefficients = 8 , 3 , -7 , -2 , 1

10) Variables = 11x , 2x , -4y

Constants = 8

Coefficients = 11 , 2 , -4 , 8

Answer: They are parallel

Step-by-step explanation:

If two lines are parallel , then they must have the same slope and if two lines are perpendicular , the product of their slope must be -1.

To check this , we must calculate the slope of the two lines given.

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

from the first point

$y_{1}$ = 2

$y_{2}$ = 1

$x_{1}$ = 5

$x_{2}$ = -1

substituting the values

slope 1 = 1 - 2 / -3 - 5

slope1 = -1 / -8

slope 1 = 1/8

Using the same format to calculate the slope of the second line

$y_{1}$ = -2

$y_{2}$ = 0

$x_{1}$ = -1

$x_{2}$ = 15

slope 2 = 0 - (-2) / 15 - (-1)

slope 2 = 2/16

slope 2 = 1/8

Since slope 1 = slope 2 , this implies that the lines are parallel
