$( \frac{2}{3} - \frac{1}{6} )$ ÷ $( \frac{2}{5} - \frac{1}{3} )$
The first thing you must do it to solve the fractions inside the parentheses first
$\frac{2}{3} - \frac{1}{6} = \frac{4}{6} - \frac{1}{6}$ which is $\frac{3}{6} or \frac{2}{3}$ because you must get a common denominator in order to solve. The common denominator is 6. So you must multiply in order to get 6. $\frac{2}{3} *6= \frac{3}{6}$ Then you do the other fraction: $\frac{2}{5} - \frac{1}{3}= \frac{6}{15} - \frac{5}{15}$ which is $\frac{1}{15}$ because 15 is the common denominator and you must multiply the denominator to get 15, thus, you must multiply by the same amount for the numerator. So now it is $\frac{3}{6}$ ÷ $\frac{1}{15}$ but when dividing, you just need to flip-flop the second fraction and then multiply across. Now it is $\frac{3}{6} * \frac{15}{1} = \frac{45}{6}$ But to simplify, you find a common factor which is 3.
45÷3=15 and 6÷3=2 which is now $\frac{15}{2}$
You answer is C) $\frac{15}{2}$

Write an equation in slope -intercept form for a line that passes through (-2,7) and (14,21)

Georgia [21]

(-2,7) and (14,21)

Find the slope by using the formula $m = \frac{y2 - y1}{x2 - x1}$

Plug in the numbers. $m = \frac{21 - 7}{14 - - 2} 
 \\ m= \frac{14}{16} = \frac{7}{8} 
$

Write it in point slope form first

y - y1 = m(x - x1)
y - 7 = 7/8(x - -2)
y - 7 = 7/8x + 1.75
+ 7 +7

y = 7/8x + 8.75

Our final equation would be: <span>y = 7/8x + 8.75</span>
