What do we know about the slope of a line perpendicular to another line where the slope is known??
Speak.
You rang?
What is the slope of the line that is given in the problem?
Y = -X + 6 That is the line equation of the line that is given. What is the slope of that line ??
Are you prepared to work on line equations?
oh sorry i had left slope of Y = -X + 6 is -1
Very good, now what would the slope of the line that is perpendicular to that line be?
??
Have you ever heard the term "reciprocal"?
yes
reciprocal : The multiplicative inverse of a number. For example, 2 divided by 3 is the reciprocal of 3 divided by 2.
thats what i have learned (it definition )
Good you will need to know what reciprocal means, a perpendicular line to that given line will have a slope that is the "negative reciprocal" of the slope of the given line. What is the negative reciprocal of -1 ?
1
To keep within the bounds of your definition look at -1 as -1/1 The reciprocal of -1 is 1/-1 or -1 Now the negative of that is 1, yes, I see you have already figured that out. Great lets move on.
Use the slope formula: We know that the slope will be a positive 1, and the slope is defined as change in y divided by the change in x (delta y/delta x)|dw:1372689737452:dw|
