The equation of line r is y = -1\2x - 4. If line s runs perpendicular to line r and passes through (4, -3), what would be the eq

Scrat [10]

First off, what's the slope of "r" anyway, $\bf y=\stackrel{slope}{-\cfrac{1}{2}}x-4$ .

low and behold, since "r" is in slope-intercept form, notice, it has a slope of -1/2.

now, any line perpendicular to "r", will have a negative reciprocal slope to it, that is,

$\bf \textit{perpendicular, negative-reciprocal slope for slope}\quad -\cfrac{1}{2}\\\\
negative\implies +\cfrac{1}{{{ 2}}}\qquad reciprocal\implies + \cfrac{{{ 2}}}{1}\implies 2$

so we're really looking for a line whose slope is 2, and runs through 4,-3,

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1\\
% (a,b)
&&(~{{ 4}} &,&{{ -3}}~)
\end{array}
\\\\\\
% slope = m
slope = {{ m}}\implies 2
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-(-3)=2(x-4)\implies y+3=2x-8
\\\\\\
y=2x-11$

collins bottle of water is 5/6 full.After school the bottle is 1/3 full. Write the difference of the amounts before school and a

Anettt [7]

Answer: 1/2 of the bottle

Step-by-step explanation: Hi there,

To do this, we need to have a common denominator (The lower number). To do this, we can multiply the numerator (top) and denominator (bottomem) by 2 and it will not change the value. We can do this because we are multiplying by 2/2, which is the same as 1. By doing this, you end up with 2/6 (because 1/3 * 2/2 = 2/6) and now we can subtract. To subtract 5/6 and 2/6, you can subtract the numerators (top) and leave the denominator the same. 5/6 - 2/6 = 3/6, or 1/2, thus he drank 1/2 of the bottle.
