Answer:
m=3
Step-by-step explanation:
Perpendicular lines intersect at 90 degrees or perpendicular angles. As such, their slopes are related. The slope of each line is the negative reciprocal of the other. For the equation, 
. The slope or 
. This means the slope of the other line will be the negative reciprocal which is -(-3)=3
5x+5=6.4-2.7x
7.7x=1.4
x=1.4/7.7
x=0.181818...
0.2(6x+1)=0.5x
1.2x+0.2=0.5x
0.7x=-0.2
x=-0.2/0.7
