Line E passes through the points (2, 3) and (4, -3). What is the slope of a line perpendicular to line E?

lilavasa [31]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~ 2 &,& 3~) 
% (c,d)
&&(~ 4 &,& -3~)
\end{array}
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-3}{4-2}\implies \cfrac{-6}{2}\implies \cfrac{-3}{1}$

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus

$\bf \textit{perpendicular, negative-reciprocal slope for}\quad \cfrac{-3}{1}\\\\
negative\implies +\cfrac{3}{ 1}\qquad reciprocal\implies +\cfrac{ 1}{3}\implies \cfrac{1}{3}$

Find the slope of the line whose equation is 5y = x - 3.<br> a)-3<br> b)-3/5<br> c)1/5<br> d)5

Wewaii [24]

Y=mx+b
m=slope
solve for y

5y=x-3
divide both sides by 5
y=(1/5)x-(3/5)
slope=1/5

C is answer

Alberto invests his $90 for 2 years at r % per year simple interest.

Sloan [31]

Answer:

rate=55 percent

Step-by-step explanation:

SI=PRT

p=90

r=?

t=2

si=99

R=SI÷PT

R=99÷90×2

r=99÷180=0.55

r=0.55×100

R=55%

Help with this plaese

WARRIOR [948]

So the rise over run is 5/-4
To start off take 10 degrees/96 cups
If you look at the pattern the degrees go up by 5 and the cups go down by 4

So I believe the answer should be
25 degrees = 84 cups
