a.

Answer to Problem 12CR
Explanation of Solution
Given information :
Given equation of line and a point
Firstly write the given equation in slope intercept form and find the slope.
Solve the given equation for y.
Slope of this line is:
The slope of parallel lines are always same.
So,
Find the value of b to use the point (-8,3)
Write the equation of parallel line.
b.
The equation of line that is perpendicular to the given line.
b.

Answer to Problem 12CR
Explanation of Solution
Given information :
Given equation of line and a point
Firstly write the given equation in slope intercept form and find the slope.
Solve the given equation for y.
Slope of this line is:
The slope of perpendicular lines are negative reciprocal of the given line’s slope.
So, slope of perpendicular line is:
Find the value of b to use the point (-8,3)
Write the equation of parallel line.
