Answer:

1/2

Step-by-step explanation:

Okay so the find slope you have the put the line in y-mx+b form.  In -2x+4y=16 to get 'y' by its slef you have to add 2y to each side.  4y=16+2x then you have to divide by 4 to get y alone.  y=4+1/2x

Your slope is 1/2

What is the best way to classify each equation? 22-3x+7x=4(x+5) ,6(2x-3=3(3-5), 6x-14=2(3x-7), 6x+3(x-4)=8(x-3)
Romashka-Z-Leto [24]
1. 22 - 3x + 7x = 4(x + 5)
   22 - 3x + 7x  = 4x + 20
  <u>      +3x  +3x   +3x          </u>
         22 + 10x = 7x + 20
        <u>          -7x   -7x        </u>
           22 + 3x = 20
          <u>-22         -22</u>
                   <u>3x</u> = -<u>2</u>
                    3      3
                     x = -2/3

2. 6(2x - 3) = 3(3 - 5)
    12x - 18 = 3(-2)
    12x - 18 = -6
    <u>       +18   +18</u>
           <u>12x</u> = <u>12</u>
            12     12
               x = 1

3. 6x - 14 = 2(3x - 7)
    6x - 14 =  -3x
    6x - 14 = 2(-7)
    6x - 14 = -14
    <u>     +14   +14</u>
           <u>6x</u> = <u>0</u>
            6     6
             x = 0

4. 6x + 3(x - 4) = 8(x - 3)
    6x + 3x - 12 = 8x - 24
            9x - 12 = 8x - 24
           <u>-8x          -8x        </u>
              x - 12 = -24
              <u>   +12    +12</u>
                     x = -12
