Step 1

Given line is:

Equation of a line in slope-intercept form is y = mx + c, where m is the slope and c is the intercept.

Comparing to the given equation, slope and y – intercept are given by:

Step 2

When two lines are parallel, the slopes will be equal.

Hence, the slope of a line parallel to the given line is:

Step 3

When two lines are perpendicular, the product of slopes is -1.

Let the slope of the perpendicular line to the give...
