Use the substitution method or linear combinations to solve the linear system and tell how many solutions the system has. $$ \begin{aligned}&15 x-5 y=-20\\\&-3 x+y=4\end{aligned} $$
Use the graphing method to solve the linear system and tell how many solutions the system has. $$ \begin{aligned}&x+y=8\\\&x+y=-1\end{aligned} $$
Graph the system of linear equations. Does the system have exactly one solution, no solution, or infinitely many solutions? $$ \begin{array}{l}-6 x+2 y=4 \\\\-9 x+3 y=12\end{array} $$
You are climbing a 500 -foot cliff. By 1: 00 P.M. you have climbed 125 feet up the cliff. By 4: 00 P.M. you have reached a height of 290 feet. What is your rate of change in height?
