Question

Find the equation of the line containing the given point and slope.  (-4, 1) m=2/5

anonymous · Answer

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.

anonymous · Answer

Sorry...remove the open parenthesis at the front of the point-slope form.

anonymous · Answer

I you need it in slope-intercept, solve the above answer for y (after plugging in the values).

anonymous · Answer

yah I tried that and I must of distributed something wrong

anonymous · Answer

can you post your work?  I can look to see where you might have goofed.

anonymous · Answer

When I distributed 2/5 to x-(-4) i got 2/5x -8/5 which is where i probably got something wrong

anonymous · Answer

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.

anonymous · Answer

ok, its still showing wrong, all they want is they equation

anonymous · Answer

I get y=(2/5)x + (13/5)

thank you!
