find the coordinate of the foot of the perpendicular from (6,8) to the line joining the points (1,5) and (9,3).

(5,4)

Step-by-step explanation:

(1,5)and(9,3) then

(x1+x2)/2,(y1+y2)/2 ie the coordination of the foot of the perpendicular

1+9÷2,5+3÷2

5,4

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
