so let's use those two points the line passes through to get its slope.

\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-12}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-12-0}{4-2}\implies \cfrac{-12}{2}\implies -6

\frac{3}{4} ( \frac{1}{2} x-12)+ \frac{4}{5} = 

=\frac{3}{4} ( \frac{x}{2} -12)+ \frac{4}{5}

= \frac{3x}{8} -9+ \frac{4}{5}

= -\frac{41}{5} + \frac{3x}{8}


The answer is: -\frac{41}{5} + \frac{3x}{8}

Louis has three more quarters than dimes in his pocket, for a total of $1.80. which of the following equation could be used to d
vodka [1.7K]
Number of dimes: x
Number of quarters:  x + 3
Answer:
B ) 0.10 x + 0.25 ( x + 3 ) = $1.80
Also we can solve this equation:
0.10 x + 0.25 x + 0.75 = 1.80
0.35 x = 1.80 - 0.75
0.35 x = 1.05
x = 1.05 : 0.35
x = 3,  x  + 3 = 6
He has 6 quarters and 3 dimes. 
( 6 * 0.25 + 3 * 0.10 = 1.50 + 0.30 = $1.80 - correct)
