Describe what is meant by the slope of a non-vertical line. Explain how your description relates to the definition of slope.

Answers

Answer:  A verticle line does not have a slope.

Step-by-step explanation:  Slope is the rate of change of y for each change in x.  y = 2x is a line with slope of 2.  Each time x is incremented by 1, y will increase by twice (2x) that amount.  There is no slope to a verticle line, unless you want to call it infinite.  The value of y is not defined by x.

Quick answer: The fourth option, (-2, -1) and (-8, 3)

Explanation: so for this equation we are determining which coordinates are in the graph, now it wants us to be looking at q—>N so we can immediately rule out A and B since they would be on the line past Q in the wrong way, now we look at the second pair of numbers since the first ones are the same for C and D, we see that Cs is at 3, -8 and since this is both past Q to the right and it doesn’t lie on the line we can conclude that the answer is D. We can the check this by looking at the 2 points on the line.

What is 38 + 7k = 8(k + 4)

Answers

Steps

38 + 7k = 8k + 32

38 + 7k - 38 = 8k + 32 - 38

7k = 8k - 6

7k - 8k = 8k - 6 - 8k

-k = -6

-k/-1 = -6/-1

k = 6

Answer

k = 6

Find the value of x.

Answers

So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:

[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]

And now just solve for x!

[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]

So, your answer is:

x = -2.4

The value of X
X = -2.4

Answer:

All you need to do is plug the values and then simplify!

[tex] \large{ \tt{ - 2x + 3y}}[/tex]

Plug the value of x and y :

[tex] \longrightarrow \: \large{ \tt{ - 2 \times ( - 2) + 3 \times ( - 5)}}[/tex]

When negative integer is multiplied by negative integers , we get positive integer & when positive integer is multiplied by negative integer , we get negative integer.

[tex] \longrightarrow \large{ \tt4 + ( - 15){}}[/tex]

[tex] \longrightarrow \large{ \tt{4 - 15}}[/tex]

[tex] \longrightarrow{ \large{ \boxed{ \tt{ - 11}}}}[/tex]

Hence , Our simplified answer is -11 .

Answers

Answer:

point slope form: y + 4 = 3/8 (x + 5)       slope intercept: y = 3/8x - 17/8

Step-by-step explanation:

y2 - y1 / x2 - x1

-1 - (-4) / 3 - (-5)

slope = 3/8

y + 4 = 3/8 (x + 5)

y = 3/8x + b

-1 = 3/8(3) + b

-1 = 9/8 + b

-17/8

y = 3/8x - 17/8

Answer:

11/15

Step-by-step explanation:

Answer:

- 11 / 15

Step-by-step explanation:

x = - 2

y = - 1 / 5

1 / 3 + x . z

= 1 / 3 + ( - 2 ) . ( - 1 / 5 )

= 1 / 3 + ( - 2 . - 1 ) / 5

= 1 / 3 + 2 / 5

1 / 3

= ( 1 / 3 ) x ( 5 / 5 )

= ( 1 x 5 ) / ( 3 x 5 )

= 5 / 15

2 / 5

= ( 2 / 5 ) x ( 3 / 3 )

= ( 2 x 3 ) / ( 5 x 3 )

= 6 / 15

1 / 3 + 2 / 5

= 5 / 15 + 6 / 15

= ( 5 + 6 ) / 15

= 11 / 15

It's hard to see your photo but if that say m∠T than your answer would be

m∠ L.

The drawings are saying the the triangles are congruent which means all the interior angles of one triangle are congruent to the angles of the second triangle.    m∠M = m∠J,   m∠K = m∠E and m∠L = m∠T

Since you have two of the angles, you can also determine what m∠L and m∠T is equal to.  The sum on all interior angles must be 180 degrees.

180 - 86 - 32 = 62

Angle L is the what you should put for your answer
