The parallel lines have the same slope. So we should check the slope from all the options. We will use formula
m = (y₂ - y₁) / (x₂ - x₁)

First Option
(x₁,y₁) = (-8,8)
(x₂,y₂) = (2,2)
Find the slope (m)
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 - 8)/(2 + 8)
m = -6/10
m = -3/5
It has the same slope of -3/5, so it's parallel with the line.

Second Option
(x₁,y₁) = (-5,-1)
(x₂,y₂) = (0,2)
Find the slope (m)
m = (y₂ - y₁) / (x₂ - x₁)
m = (2 + 1) / (0 + 5)
m = 3/5
It doesn't have the same slope, so it's not parallel with the line.

Third Option
(x₁,y₁) = (-3,6)
(x₂,y₂) = (6,-9)
Find the slope (m)
m = (y₂ - y₁) / (x₂ - x₁)
m = (-9 - 6) / (6 + 3)
m = -15/9
m = -5/3
It doesn't have the same slope, so it's not parallel with the line

Fourth Option
(x₁,y₁) = (-2,1)
(x₂,y₂) = (3,-2)
Find the slope (m)
m = (y₂ - y₁) / (x₂ - x₁)
m = (-2 - 1) / (3 + 2)
m = -3/5
It has the same slope of -3/5, so it's parallel with the line.

Fifth Option
(x₁,y₁) = (0,2)
(x₂,y₂) = (5,5)
Find the slope (m)
m = (y₂ - y₁) / (x₂ - x₁)
m = (5 - 2) / (5 - 0)
m = 3/5
It doesn't have the same slope, so it's not parallel with the line.

SUMMARY
The parallel lines are first option and fourth option

Help me with this porportional relationship please:
Reika [66]

Answer:

y = 4.5 x

Step-by-step explanation:

If this is a proportional relationship, we can find the slope

m = (y2-y1)/(x2-x1)

m = (27-0)/(6-0)

m = 27/6

m=9/2

The slope is 9/2

The y intercept, where it crosses the y axis is 0

Using the slope intercept form of the equation y=mx+b

y = 9/2 x+0

y =9/2x

It wants the decimal form

y = 4.5 x

How to solve #12 can't seem to figure it out after spending 20 mins on it
Ilia_Sergeevich [38]
The area of one of the triangular lateral faces is

\dfrac{401.48-166.28}6=39.2

You're told that the slant height, which is the same as the height of the triangular face, is 9.8, so you have

39.2=\dfrac12\times9.8\times b

where b is the length of the base of the triangle, which is also the same as the side length of the base of the pyramid. So

b=8

Select steps that could be used to solve the equation 1 + 3x = -x + 4.
Olegator [25]

Answer:

A, C & D

Step-by-step explanation:

A) 1 + 3x = -x + 4  {subtract 1}

  1 + 3x -1 = -x + 4 - 1

       3x     = -x + 3         {add x}

     3x + x = -x + 3 + x

        4x    = 3       {Divide by 4}

       4x/x = 3/4

x = 3/4

C) 1 + 3x = -x +4            {Add x}

  1+ 3x + x = - x +4 + x      

   1 + 4x  = 4    {subtract 1}

        4x = 4 - 1

        4x = 3   {Divide by 4}

D) 1 + 3x = -x + 4        { Subtract 3x}

         1    = -x + 4 -3x

         1 = -4x + 4          Subtract 4}

      1 - 4 = -4x

        -3 = -4x              {Divide by -4}

       -3/-4 = x

x = 3/4  

          x = 3/4
