First you do 6-3 which is 3 then divide it by 18 which is 6 then add it by 7 which is 13
First off, nicely done on the exponents. You'd be surprised on how bad some look ,:D
a)

b)
The slope of the parallel line is 0 and the slope of the perpendicular line is undefined
<h3>How to determine the slope?</h3>
The equation is given as:
y = 1
A linear equation is represented as:
y = mx + c
Where:
m represents the slope
By comparison, we have:
m = 0
The slope of the parallel line is:
Slope = m
This gives
Slope = 0
The slope of the perpendicular line is:
Slope =-1/m
This gives
Slope = -1/0
Slope = undefined
Hence, the slope of the parallel line is 0 and the slope of the perpendicular line is undefined
