point d is the foot of the
perpendicular from the point o(2, -3)
to the line y = 3x + 1.
(i) Find the length of DO.
(ii) Find the coordinates of the
reflection of A in the line y = 3x + 1
​

Respuesta :

Answer:

(I) using the equation y=3x+1 at x=2 the length of Line DO is y=3(2)+1

Therefore y=7

(II) the coordinates At x=-3

Y=3(-3)+1=-8

Hence from (I) above also the coordinates are (7,-8)

Step-by-step explanation:

Step 1 :you declare variables

Step 2: you solve the equation at both points on the graph
