What is the slope of y = -3x = 2?
y = –3x + 3 y = –3x – 9 y = x – 1 y = x + 19
y = -3x+2, what is it's slope?
No, sweetheart, that is not right.
Those are the choices for answers and he/she is asking you to just pick one and give the answer.
That's why I kept asking you what the slope is. Because the slope of the perpendicular is the negative reciprocal of the slope of the given line.
Well none of those are correct.
Because none have slope 1/3
Agree. But, the "asker" is absent. So, I don't know what to say.
Well, maybe you should just solve it for her and then we can leave.
y= -3x + 2 has slope -3. The slope of a line perpendicular to y=-3x+2 will have slope 1/3 because the slope product of two perpendicular lines = -1 ( with the exception of a vertical line and a horizonal line). Use the point-slope formula, y -y sub 1 = m (x - x sub 1) where (x sub1, y sub) is the point with coordinates (6, 1). y - 1 = (1/3)( x - 6) y -1 = (1/3)( x ) - 2 y -1 = (1/3) (x) - 2 y - 1 = (1/3) x - 2 y = (1/3) x - 1 ----> Choice not given
@ Mertsj Speaking for myself, the use of condescending language such as "sweetheart" is inappropriate here. Reference "No, sweetheart, that is not right." above. http://dailyplateofcrazy.com/2010/03/26/terms-of-endearment-let-me-call-you-sweetheart/
its is asking for PARALLEL THAT IS WHY .
