A line includes the points (10,-5) and (-10,-1). What is the equation in slope intercept form?
Elodia [21]

\bf (\stackrel{x_1}{10}~,~\stackrel{y_1}{-5})\qquad (\stackrel{x_2}{-10}~,~\stackrel{y_2}{-1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-(-5)}{-10-10}\implies \cfrac{-1+5}{-20}\implies \cfrac{4}{-20}\implies -\cfrac{1}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-5)=-\cfrac{1}{5}(x-10) \\\\\\ y+5=-\cfrac{1}{5}x+2\implies y=-\cfrac{1}{5}x-3

9 over 3x = 4 over x + 2
Elan Coil [88]

The equation that we have been given is:

\frac{9}{3x}  =  \frac{4}{x+2}

In order to solve for the value of 'x', we'll have to use cross-multiplication.

Cross-multiplication is a method in which the numerator of one fraction is multiplied by the denominator of another fraction that it is equal to.

Let's cross-mutliply the numerators and denominators:

\frac{9}{3x}  =  \frac{4}{x+2}

9*(x+2) = 4*(3x)

Distribute the numbers into the parentheses.

9x + 18 = 12x

Simplify by subtracting both sides by 9x:

9x - 9x + 18 = 12x - 9x

0 + 18 = 3x

18 = 3x

3x = 18

Divide both sides by 3:

\frac{3x}{3} = \frac{18}{3}

<u>x = 6</u>

<u></u>

Let me know if you'd like me to explain anything I did here.
