Paralell lines have the same slope
perpendicular lines have slopes that multiply to get -1
neither is niegher
so
y=mx+b
m=slope
x=y+2
minus 2
x-2=y
y=x-2
y=1x-2
slope is 1
y=x+3
y=1x+3
1=1
they are paralell

<span>8 - 2b = -2/3(12b + 6)
8 - 2b = -8b -4
8 + 4 = -8b + 2b
12 = -6b
b = -12/6
b = -2
So, your final answer is b = -2</span>
⓵ Write down both equations :
X ÷ 3 = 700
X ÷ 7 = 300
⓶ Solve both of these equations :
X ÷ 3 = 700
× 3 × 3
↓
X = 2100
X ÷ 7 = 300
× 7 × 7
↓
X = 2100
Now that you’ve solved each equation and that “X” is worth the same thing in both, you know that you calculated everything correctly!
If you really want to triple check your answers, you could test that number to see if it works :
2100 ÷ 3 = 700? → YES
2100 ÷ 7 = 300? → YES
↠ So the answer to your question is : The number is 2100.
I really hope this helped, if there’s anything just let me know! ☻
