Please look in your text book for this problem Statement  The given pair of parallel lines .

Find an equation of line perpendicular to the given pair of lines.

The slope of perpendicular line is the opposite resiprocal of 4 that is .

Use the y-intercept of the line , , as one of the end points of the perpendicular line. (Write the slope intercept form) (Sustitute ) (Simplify) Find the point of intersection between and using a system of equations. (Write the equation) (Substitute ) (Group like terms on each side) (Simplify) (Divide each side by ) Substitute in the equation to find the value of y. (Write the equation) (Substitute ) (Simplify)

So, the point of intersection is .  Use the distance formula to determine the distance between . (Write the distance formula) (Substitute ) (Simplify) The distance between pair of parallel lines is or 4.12. TESTIMONIALS
