Answer:

B: One

Step-by-step explanation:

As shown on the graph, they are intersecting at only one point, so the answer is one. If it was infinite it would be the same line. If it had no solution the lines would be parallel.

\sf{\red{Answer}}

\sf{m =  \frac{1}{2} }

\sf{\purple{Explanation}}

\sf{m =  \frac{y_{2}- y_{1}}{m_{2} - m_{1}} }

\sf{m =  \frac{9- 3}{7- ( - 5)} }

\sf{m =  \frac{6}{7 +  5} }

\sf{m =  \frac{6}{12} }

\sf{m =  \frac{1}{2} }

Answer: 15, -8

Step-by-step explanation:

u_2=7\\u_2=u_1+r\\u_3=u_1+2r\\u_4=u_1+3r\\\\u_1+u_2+u_3+u_4=4u_1+6r=12\\u_1+r=7\\\\

\left \{ \begin {array} {ccc|c|c}u_1+r&=&7&-4&-6\\4u_1+6r&=&12&1&1\\\end {array} \right.\\\\\\\left \{ \begin {array} {ccc}2r&=&-16\\-2u_1&=&-30\\\end {array} \right.\\\\\\\left \{ \begin {array} {ccc}r&=&-8\\u_1&=&15\\\end {array} \right.\\\\\\Proof:\\u_1=15\\u_2=7\\u_3=-1\\u_4=-9\\sum=12\\
