Question

Two lines c and d are represented by the following equation

Answer 1

$\begin{gathered} y=x+5 \\ y=-2x-1 \end{gathered}$

we can replace the y of the first equation on the second and solve x

$\begin{gathered} x+5=-2x-1 \\ x+2x=-1-5 \\ 3x=-6 \\ x=-\frac{6}{3} \\ x=-2 \end{gathered}$

now replace the x on any equation yo find y( i will use the first eq)

$\begin{gathered} y=(-2)+5 \\ y=3 \end{gathered}$

so, the solution is (-2,3), this happens because the two lines meet at this point

option B
