m(x-x1) = (y-y1)
OpenStudy (anonymous):
-4=1/2(1) + b
-9/2 = b
y=1/2x -9/2

lol ima make u fail

Wrong answer buddy.
OpenStudy (anonymous):
3.5?

Its not one of the options
hero (hero):
y = .5x - 4.5
OpenStudy (anonymous):
haha my answer right?
hero (hero):
apparently
OpenStudy (anonymous):
Not an option either /:

The answer might be in a different form

For saying unnecessary stuff that's disrespectful
OpenStudy (anonymous):

im mad i got it wrong
OpenStudy (anonymous):
y - 4 = 1/2(x - 1)
y + 4 = 2(x - 1)
y + 4 = 1/2(x - 1)
y - 4 = 2(x + 1)
OpenStudy (anonymous):
wow i got banned -__-
myininaya (myininaya):
\[y-(-4)=\frac{1}{2}(x-1)\]
\[y+4=\frac{1}{2}x-\frac{1}{2}\]

It's the third option
OpenStudy (anonymous):
follow this equation y-y1=m(x-x1) = y-(-4)=1/2(x-1) resolve algebraically and the answer is -4.5
hero (hero):
I just simplified to y = mx+b instead of leaving it in point-slope form.
OpenStudy (anonymous):
oh i forgot in slope intercept form y=1/2x-4.5
