Give the location of the following ordered pairs using the graph below.
- \begin{align*}A\end{align*}
- \begin{align*}B\end{align*}
- \begin{align*}C\end{align*}
- Graph \begin{align*}y=\frac{7}{3} x-4\end{align*}.
- Find the slope between –3, 5) and (–1.25, –2.25).
- Find the intercepts of \begin{align*}6x+9y=54\end{align*}.
- In 2004, the high school graduation rate in the state of New Jersey was 86.3%. In 2008, the high school graduation rate in New Jersey was 84.6%. Determine the average rate of change. Use this information to make a conclusion regarding the graduation rate in New Jersey (source: http://nces.ed.gov/pubs2010/2010341.pdf).
- Identify the slope and \begin{align*}y-\end{align*}intercept of \begin{align*}4x+7y=28\end{align*}.
- Identify the slope and \begin{align*}y-\end{align*}intercept of \begin{align*}y=\frac{-3}{5} x-8\end{align*}.
- Graph \begin{align*}y=9\end{align*}.
- Graph the line containing (3, 5) and (3, –7). What type of line have you created?
- The number of cups of milk is directly proportional to the number of quarts. If 26 quarts yields 104 cups of milk, how many cups of milk is 2.75 quarts?
- Graph the direct variation situation using the table below:
\begin{align*}&0 && 1 && 2 && 3 && 4 && 5 && 6 && 7\\ & 0 && 2.25 && 4.5 && 6.75 && 9 && 11.25 && 13.5 && 15.75\end{align*}
- \begin{align*}h\end{align*} varies directly as \begin{align*}m\end{align*} when \begin{align*}m=4,h=27\end{align*}. Find \begin{align*}h\end{align*} when \begin{align*}m=-5.5\end{align*}.
- \begin{align*}h(n)=\frac{1}{2} |6-n|+11\end{align*}; find \begin{align*}h(25)\end{align*}
- Are these lines parallel? \begin{align*}y=-2x+1\end{align*} and \begin{align*}y=2x-1\end{align*}
- Mixture \begin{align*}A\end{align*} has a 2% hydrogen solution and mixture \begin{align*}B\end{align*} has a 1.5% hydrogen solution. How much of mixture \begin{align*}B\end{align*} needs to be added to 6 ounces of mixture \begin{align*}A\end{align*} to obtain a value of 0.51?
