Question 503027: A line perpendicular to x + 3y = 5 passes through (1, -1). What is the equation of the line in standard form?
The way I tried is
x + 3y = 5
x + 5 = 3y
y = 1x + 5/3
Slope is 1.
y - 1 = 1(x + 1)
y = 1
Am I doing this right?

Question 503517: 1) 1/2q-5>3Q
This is what i have so far and am stuck.
1q-5>3q
2) 13x-5=x+1
3)Not sure if the answer is right. But I did tried
3/4q+11=4q+37
3q+44=16q+148
16q+148=3q+44
148 +60
16q = 3q+60
-3 -3
13 = 60
Divdie both sides by 13 answer is -4
4) 2/3y-7=5y+19
3y-21=15y+57
15y+57=3y-21
57 +57
15y = 3y-36
-3 -3
12y = 36
divide by 12 on both sides Answer 3
5)5z-3>3z+1
