Answer:

Slope of line M= -5

Step-by-step explanation:

Perpendicular lines have opposite reciprocals for slope.

For ex: 1/2x=y is perpendicular to -2x=y

For this one simplify the first equation:

x+1=5y

x/5+1/5=y

The slope of the original equation is 1/5.

So the slope of the perpendicular line would be -5.

The actual equation would be:

-5x+19=Y
