Any particular form of the equation? I'd use point-slope form:
\[(y-y_{1}=m(x-x_{1})\]
where the given point is \[(x_{1},y_{1})\] and m is the given slope.
OpenStudy (anonymous):
Sorry...remove the open parenthesis at the front of the point-slope form.
OpenStudy (anonymous):
I you need it in slope-intercept, solve the above answer for y (after plugging in the values).
OpenStudy (anonymous):
yah I tried that and I must of distributed something wrong
OpenStudy (anonymous):
can you post your work? I can look to see where you might have goofed.

When I distributed 2/5 to x-(-4) i got 2/5x -8/5 which is where i probably got something wrong
OpenStudy (anonymous):
Ahh...x-(-4) = x+4. so you should get 2/5x+8/5.
Not switching the sign when subtracting a negative is an all too common mistake.
OpenStudy (anonymous):
ok, its still showing wrong, all they want is they equation
OpenStudy (anonymous):
I get y=(2/5)x + (13/5)
OpenStudy (anonymous):
thank you!
