step 1
Find out the slope of the given line
we have
8x-y=9
isolate the variable y
y=8x-9
the slope is m=8
step 2
Remember that
If two lines are parallel then their slopes are equal
that means
The slope of the parallel line is m=8
step 3
Find out the equation in slope-intercept form
y=mx+b
we have
m=8
point (8,2)
substitute and solve for b
2=8(8)+b
b=2-64
b=-62
the equation in slope-intercept form is
step 4
Find out the equation in standard form
Ax+By=C
where
A is a positive integer
B and C are integers
we have
y=8x-62
