Answer:

5) C pink 6) A -1/2x + 1/4 7) D z ≥ 0

Step-by-step explanation:

5) White 1/6 = 4/24

Green 1/3 = 8/24

Pink 1/8 = 3/24

Yellow 3/8 = 9/24

6) 11/2x - 2(3x - 1/8) Distribute the -2

11/2x - 6x + 1/4 Combine like terms

-1/2x + 1/4

7) z ≥ 0

z is greater than or equal to 0

I am trying to find the equation of the following lines, i’m just having trouble putting them in slope-intercept form.

Margaret [11]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1\\
&&(~ -1 &,& -6~)
\end{array}
\\\\\\
slope = m\implies \cfrac{2}{5}
\\\\\\
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-(-6)=\cfrac{2}{5}[x-(-1)]
\\\\\\
y+6=\cfrac{2}{5}(x+1)\implies y+6=\cfrac{2}{5}x+\cfrac{2}{5}
\\\\\\
y=\cfrac{2}{5}x+\cfrac{2}{5}-6\implies y=\cfrac{2}{5}x-\cfrac{28}{5}$

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
&&(~ -2 &,& 5~) 
&&(~ 5 &,& 8~)
\end{array}
\\\\\\
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{8-5}{5-(-2)}\implies \cfrac{8-5}{5+2}\implies \cfrac{3}{7}
\\\\\\
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-5=\cfrac{3}{7}[x-(-2)]
\\\\\\
y-5=\cfrac{3}{7}(x+2)\implies y-5=\cfrac{3}{7}x+\cfrac{6}{7}
\\\\\\
y=\cfrac{3}{7}x+\cfrac{6}{7}+5\implies y=\cfrac{3}{7}x+\cfrac{41}{7}$
