Question

Determine the equation of the line, in point-slope form, that will get your spacecraft from Point A to Point B.
Point A: (1,4)
Point B: (3,5)

hero · Answer

Point Slope form:

$y - y_1 = m(x - x_1)$

anonymous · Answer

Yeah, I know that part, I'm just confused about where to plug the numbers in

hero · Answer

Only $x_1, y_1$ and $m$ need to be filled in

hero · Answer

$(x_1,y_1) = (1,4)$

hero · Answer

$m = \dfrac{y_2 - y_1}{x_2 - x_1}$

anonymous · Answer

oh okay, and m is the slope, but i'm not sure how to fund that

anonymous · Answer

*find

hero · Answer

$(x_2, y_2) = (3,5)$

hero · Answer

$m = \dfrac{5 - 4}{3 - 1}$

anonymous · Answer

so 1 over 2

hero · Answer

$m = \dfrac{1}{2}$

So now you have everything you need to plug-in

anonymous · Answer

okay let me see if this is right 5y-4y=1/2(3-1)?

Hope I'm right! Thanks for the help! ^-^
