Find the slope of the straight line that passes through the following pair of points. \[ \begin{array}{l}(-3,1) \text { and }(2,3) \\ \text { A. The slope is the correct choice below and, if necessary, fill in the answer box to complete your choice. } \\ \text { (Simplify your answer.) } \\ \text { B. The slope is undefined. }\end{array} \text {. } \]

Find the solutions. \( \left\{\begin{array}{l}x^{2}-4 y=29 \\ x^{2}+2 y=23\end{array}\right. \) > Next Question

\( \frac { 3 ) } { 3 x + 4 } = \frac { 2 x - 8 } { 3 } \)

Use the elimination method to find all solutions of the system: \( \left\{\begin{array}{l}x^{2}-2 y=7 \\ x^{2}+5 y=14\end{array}\right. \) The two solutions of the system are: (the one with \( x<0 \) is) \( x=\square \) \( y=\square \) (the one with \( x>0 \) is) \( x=\square \) \( y=\square \)
