good day to you to request a hardcopy

Answer 2

Answer:  slope=$-\frac{l}{m}$ and y-intercept=$-\frac{n}{m}$.

Step-by-step explanation:

• To find the slope and y-intercept we need to bring the equation in its standard form.
• lx + my + n=0

   ⇒ my= -lx -n

  ⇒ $y=-\frac{l}{m}x-\frac{n}{m}$

• The standard equation of line is y=mx + c.
• Comparing with the standard equation of line we get

        slope=$-\frac{l}{m}$ and y-intercept=$-\frac{n}{m}$.

• Hence,   slope=$-\frac{l}{m}$ and y-intercept=$-\frac{n}{m}$.
