Question

Given P(8,0), Q(-4,9). Write an equation for PQ

Answer 1

PLEASE HELP ME SOLVE IT!!

Answer 2

first you want to find the slope:

\[m=\frac{ y_{2}-y _{1} }{ x _{2}-x_{1} }\]

once you have the slope you need to plug the numbers into this:
\[y-y _{1}=m(x-x _{1})\]

Answer 3

you would also have to restrict the domain if its spose to be only that line segment ...

Answer 4

if this is with vectors, then you would define the slope as a vector V, and anchor it to a point P such that:

x = Px + t Vx
y = Py + t Vy

and t = 0 to 1 is generally how that would play out
