Look at the graph shown below:

ElenaW [278]

So.. take a peek at the picture... let's get two points from it, hmm say 0,4 notice it touches the y-axis there, and say hmmm -4, 1, almost at the bottom of the line

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 0}}\quad ,&{{ 4}})\quad 
% (c,d)
&({{ -4}}\quad ,&{{ 1}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{1-4}{-4-0}$

$\bf y-{{ y_1}}={{ m}}(x-{{ x_1}})\qquad 
\begin{array}{llll}
\textit{plug in the values for }
\begin{cases}
y_1=4\\
x_1=0\\
m=\boxed{?}
\end{cases}\\
\textit{and solve for "y"}
\end{array}\\
\left. \qquad \right. \uparrow\\
\textit{point-slope form}$

once you get the slope and solve for "y", that'd be the equation of the line.

A bag contains 4 red balls, 2 green balls, 3 yellow balls, and 5 blue balls. Find each probability of randomly removing balls wi

zzz [600]

Altogether balls 4+2+3+5=14
P(red)=4/14=2/7
P(green)=2/14
P(yellow)=3/14
P(blue)=5/14
because it goes with replacement these probabilities are constant

What is the vertex form of this and how do you graph this

luda_lava [24]

set it up like a y= equation.

which would be y=-x^2+7

to find the vertex, you substitute the 0s.

so 0=-(0)^2+7

-0^2=0

0+7=7

0=7

(0,7)
