Question

Write the point-slope form of the equation of a line with slope 2/5  that passes through the point (-3,-6)

mathmale · Answer

What does the point-slope form look like?  

$$y-y _{1}=m(x-x _{1})$$
You are given x, y and b.  Plug these values into the equation to find the specific equation for this situation.

jordans_openstudy · Answer

so would "b" be "m'?

welshfella · Answer

Yes

greatlife44 · Answer

What do you think it is?

mathmale · Answer

Sorry to contradict anyone, but no, b is not m.  b in this context is the y-intercept; m is the slope, and there's no way in which these are the same.

jordans_openstudy · Answer

so would 2/5 go where M is and then -3 for y1, and -6 for x1?

greatlife44 · Answer

yeah exactly

greatlife44 · Answer

Now put it all together

jordans_openstudy · Answer

what about x and y?

greatlife44 · Answer

what's your formula again tell  us what you're plugging those numbers into

mathmale · Answer

"Write the point-slope form of the equation of a line with slope 2/5  that passes through the point (-3,-6)."  Here the slope, m, is (2/5).  x_1 is -3.  y_1 is -6.  You need to subst. these 3 numerical values into the point-slope formula I gave your earlier.

Please review this entire conversation before proceding.

jordans_openstudy · Answer

y-(-6)=2/5(x-(-3)) ?

mathmale · Answer

If you would please enclose "2/5" inside parentheses, that'd give you the perfect response (answer).

jordans_openstudy · Answer

y=2/5x-24/5

jordans_openstudy · Answer

thats what i got from a online calculator i used

mathmale · Answer

Again, please enclose that 2/5 within parentheses, so there's no doubt to anyone that you mean 2x/5 and not 2/(5x).

mathmale · Answer

I like 2x/5 and (2/5)x, but NOT 2/5x.

jordans_openstudy · Answer

so y=(2/5)x-(24/5)

jordans_openstudy · Answer

that would be the correct answer then ?

mathmale · Answer

Yes!  Thank you for the medal.

jordans_openstudy · Answer

Not a problem! i appreciate the help.
