Answer:

Samantha: 28, Wilbert: 32, Zahir: 36.

Step-by-step explanation:

The difference of 2 ratio units corresponds to a difference of 8 years, so each ratio unit stands for 4 years.

The ratio of ages in years is ...

... 4×7 : 4×8 : 4×9 = 28 : 32 : 36

Find the slope of the line that passes through the points (−2/3, 3/4) and (5/6, −1/2).
EastWind [94]

Answer:

-\frac{5}{6}

Step-by-step explanation:

Use the slope formula :\frac{y2-y1}{x2-x1}

-1/2 is y2, 3/4 is y1, 5/6 is x2, and -2/3 is x1.

\frac{-1/2-3/4}{5/6-(-2/3)}

\frac{-5/4}{5/6+2/3}

\frac{-5/4}{9/6}

\frac{-5}{4} ÷ \frac{9}{6}

-\frac{5}{4} • \frac{6}{9}

-\frac{5}{2} • \frac{3}{9}

-\frac{15}{18}  

-\frac{5}{6}

Hope this helps! Let me know if I got it wrong.
