Best ResponseYou've already chosen the best response.2If you're not sure, the slope of y  y1 = m(x  x1) is m

Best ResponseYou've already chosen the best response.0Another alternative: The slope of \(y = mx + b\) is \(m\).

Best ResponseYou've already chosen the best response.0so would it be 1/3?

Best ResponseYou've already chosen the best response.1In the slopeintercept form: y = mx + b you should know the slope of the line is the coefficient m of the x term, right?

Best ResponseYou've already chosen the best response.2yep, the slope is 1/3 The slope of ANY perpendicular line is 3/1 (flip the fraction and flip the sign)

Best ResponseYou've already chosen the best response.23/1 reduces to 3, so that means that the answer is either choice A or B this is because choice A and B have slopes of 3

Best ResponseYou've already chosen the best response.1Where flip the fraction means find the reciprocal and flip the sign means use the opposite sign.

Best ResponseYou've already chosen the best response.0yes! I remembered that!! Alright how do we know between a and b though?

jim_thompson5910

Best ResponseYou've already chosen the best response.2Now use this to find the value of b in y = mx+b y = mx+b y = 3x + b .. plug in m = 3 (the perpendicular slope) 3 = 3(4) + b ... plug in x = 4 and y = 3 3 = 12 + b Keep going to solve for b

Best ResponseYou've already chosen the best response.23 = 12 + b 3  12 = 12 + b  12 9 = b b = 9

Best ResponseYou've already chosen the best response.2not sure how you got b = 4

jim_thompson5910

Best ResponseYou've already chosen the best response.2y = mx+b y = 3x + b .. plug in m = 3 y = 3x  9 ... plug in b = 9 So that's your perpendicular equation

Best ResponseYou've already chosen the best response.0woah! haha I have no idea either...is it b?

Best ResponseYou've already chosen the best response.2ok great, just a silly math error then I guess
