What is the slope of the line perpendicular to # y=7/4x -3 #?

Answer 1

Eva Adamson

#slope = - 4/7#

One form of the equation of a straight line is y = mx + c where m is the slope and c the y-intercept.

the equation here fits this form and by comparison # m =7/4 #

Consider 2 lines with slopes # m_1 and m_2 #

when they are perpendicular to each other then # m_1 xx m_2 = - 1 #

#rArr 7/4 xx m_2 = -1 #

# rArr m_2 = -1/(7/4) = - 4/7 #

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
