Given the coordinates, classify triangle qrt by its sides. q(-2, -1), r(1, 5), t(-8, -4)

example:

=root (-2-1)*all powr 2*+(-1-5)*all power 2* =3 root 5

then make all this stepes with RT and QT.

explanation:

we write under the root (X-X)all power 2 then (y-y)all power 2

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)

2x=70  

x=70/2

x=35

thats the answer
