Question

I need help on this math problem!

Answer 1

The slope formula is:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Your points are:

B:  (b,c)

D: (a, 0)

Now you plug in the points into the equation

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{0-c}{a-b}$

$m=\frac{-c}{a-b}$

The value that belongs in the green box is -c
