Answer:
1.15
2.-13
3.13.
4.-11
5.14
6.-12
Step-by-step explanation:
For lines to be perpendicular their slopes have to be negative reciprocals of one another, mathematically...
m1*m2=-1...in this case:
y=5x/3=1/3 so the slope of the lines is 5/3 so any line that has a slope of:
5m/3=-1,
m=-3/5 is perpendicular to the original line...

The answer is 9x - 90y = 20.
Explanation:
y = 1/10 x - 2/9
First eliminate the fractions by multiplying through by the LCM which is 90:-
90y = 9x - 20
Standard form is ax + by = c, so rearranging we get:
0 = 9x - 90y - 20
9x - 90y = 20 .
