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?

What is the value of k?

 

Hello Guest!

 

\(y=kx+7\\ P(x_P,y_P)=P(-4,-7)\\ k=-\dfrac{7-y_P}{x_P}=-\dfrac{7-(-7)}{-4}\)

\(k=3.5\)

Equation m does not matter.
