Answer:
Line "L" has the slope of 1 and line "K" has the slope of 2.
In order to graph a line with the slope of 
think of the numerator as the "rise" (how much you move up/down on the y-intercept) and the denominator as the "run" (how much you move to the side on the x-intercept)
Step-by-step explanation:
A slope of "1" is simply 
so you rise up one and move to the right once. This clearly demonstrated on line "L".
A slope of "2" is 
so you rise up two and move to the right once, as is demonstrated on line "K".
For the 2nd question, line "A" will have a slope of therefore it will move up once and then to the side three times. It will look like the image attached to this answer.
I hope this helped! Feel free to ask questions if needed!
Your first point would be on (0, 2), the vertex. Then, put a point on (-2, 22). Hope that helps!
Answer:
give full question. where is diagram.
Possible Answer:
Millimeter.
Step-by-step explanation:
Judging by the item in the question, a straw, millimeter is probably the correct measurement of the width of it.
Both expression have the same denominator: 9x²-1. Thus it must not be 0.
9x²-1=(3x-1)(3x+1)=0, resulting x=+-1/3.
Restrictions: x in R\{-1/3, 1/3}
Adding those expressions:
E=(-x-2)/(9x²-1 ) + (-5x+4)/(9x²-1)=
(-x-2-5x+4)/(9x²-1)=(-6x+2)/(9x²-1)=
(-2)(3x-1)/(9x²-1)=-2/(3x+1)
E=-2/(3x+1)
