The rate of change in the function y=x+4 is________ the rate of change of the function represented in the table.
Snezhnost [94]
Recall that the slope is the "average rate of change" of any function.

\bf y=\stackrel{slope}{1}x+4\qquad \qquad 
\begin{array}{ccll}
x&y\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
0&6\\2&8\\4&10\\6&12
\end{array}
\\\\\\
\textit{let's check what is the slope of the tabled function}\\
\textit{by using two points from it}

\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ 2}}\quad ,&{{ 8}})\quad 
%   (c,d)
&({{ 6}}\quad ,&{{ 12}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{12-8}{6-2}\implies \cfrac{4}{4}\implies 1

A rectangular picture frame measures 63 cm by 63 cm. What is the perimeter or distance around the picture frame in meters? m
Natalija [7]
Hi!

We need the perimeter in meters, so we have to turn cm into m. 
63 cm = 0.63 m

The perimeter is the sum of all side measures:
P = 0.63 + 0.63 + 0.63 + 0.63
P = 4 * 0.63
P = 2.52 m
