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
