Line m has the equation y = 3x + 5. Line n has the equation y = kx - 7. Lines m and n intersect at the point (-4, -7). What is the value of k?

**Hello Guest!**

\(kx-7=3x+5\\ x=-4\\ -4k-7=3\cdot (-4)+5\\ -k=\frac{-12+5+7}{4}\)

\(\color{blue}k=0\)

Line m has the equation y = 3x + 5. Line n has the equation y = - 7. Lines m and n intersect at the point (-4, -7).
