Need help!! What is the slope of the line through (2,-2) and (9,3)?

In-s [12.5K]

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

$y_{2} =3\\y_{1} =-2\\x_{2} =9\\x_{1} =2$

^^^Plug these numbers into the formula for slope...

$\frac{3 - (-2) }{9 - 2}$

A) $\frac{5}{7}$

^^^This is your slope

Hope this helped!

Easiest way to calculate 22% mark up from a cost of say 39.99

satela [25.4K]

Answer:

The markup amount on the cost 39.99 $ will be: 8.78 $

Step-by-step explanation:

Given

The cost = 39.99 (Let say in $)

Mark up = 22%

22% = 0.22

The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22

Markup amount = 0.22 × 39.99

= 8.78 $

Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $

How to find variables of these #2 & #3

Lubov Fominskaja [6]

So... hmmm if you check the first picture below, for 2)

we could use the proportions of those small, medium and large similar triangles like $\bf \cfrac{small}{large}\qquad \cfrac{x}{12}=\cfrac{6}{x}\impliedby \textit{solve for "x"}
\\\\\\
\cfrac{small}{large}\qquad \cfrac{z}{18}=\cfrac{6}{z}\impliedby \textit{solve for "z"}
\\\\\\
\cfrac{large}{medium}\qquad \cfrac{y}{12}=\cfrac{18}{y}\impliedby \textit{solve for "y"}$

now.. for 3) will be the second picture below

$\bf \cfrac{large}{medium}\qquad \cfrac{x+10}{2\sqrt{30}}=\cfrac{2\sqrt{30}}{10}\impliedby \textit{solve for "x"}
\\\\\\
\textit{now, because you already know what "x" is, we can use it below}
\\\\\\
\cfrac{large}{small}\qquad \cfrac{z}{x}=\cfrac{x+10}{z}\impliedby \textit{solve for "z"}
\\\\\\
\textit{and let us use "x" again below}
\\\\\\
\cfrac{small}{medium}\qquad \cfrac{y}{10}=\cfrac{x}{y}\impliedby \textit{solve for "y"}$
