M = ? B = ?
OpenStudy (anonymous):
M = 3/2 B = 5
jimthompson5910 (jim_thompson5910):
m = 3/2 is the given slope
jimthompson5910 (jim_thompson5910):
we want the perpendicular slope, so we flip the fraction 3/2 ----> 2/3
and we flip the sign 2/3 ---> -2/3

I got other answer
I need help with this
jimthompson5910 (jim_thompson5910):
making -2/3 to be the perpendicular slope
OpenStudy (anonymous):
I say B
jimthompson5910 (jim_thompson5910):
B?
OpenStudy (anonymous):
for this one

jimthompson5910 (jim_thompson5910):
B is correct for that one
OpenStudy (anonymous):
its wrong @jim_thompson5910
OpenStudy (anonymous):
jimthompson5910 (jim_thompson5910):
oh sry, not thinking
jimthompson5910 (jim_thompson5910):
they are equivalent lines since they trace out the same path exactly

so whats this one ?
jimthompson5910 (jim_thompson5910):
what's the slope of that given line?
OpenStudy (anonymous):
-1/2
OpenStudy (anonymous):
M = -1/2 B = 3
I need get 5 in a row right so please double check! i cant fail!
jimthompson5910 (jim_thompson5910):
B = 3 isn't true

jimthompson5910 (jim_thompson5910):
draw a parallel line through that point
then figure out where it crosses the y axis
OpenStudy (anonymous):
can you give me b?
OpenStudy (anonymous):
it crosses at 3/
OpenStudy (anonymous):
or is it B = 6?
jimthompson5910 (jim_thompson5910):
nope not b = 6

try this, solve for b
y = mx + b
y = (-1/2)*x + b
-5 = (-1/2)*(-5) + b
b = ??
OpenStudy (anonymous):
B = -7 ?? @jim_thompson5910
jimthompson5910 (jim_thompson5910):
very close
jimthompson5910 (jim_thompson5910):
but no, b = -7 is not the answer
