Answer 1

Solution given:

2:centroid=
`(x_1+x_2+x_3)/(3),(y_1+y_2+y_3)/(3)`

=
`(1+3+5)/(3),(2+7+3)/(3)=(3,4)`

4:

Slope:
`(y_2-y_1)/(x_2-x_1)=(6-2)/(5-3)=2`

3;

perpendicular distance =
`(ax_1+by_1+c)/(√(a²+b²))`

`(x_1,y_1)=(3,-2)`

4x-3y+2=0

comparing above equation with ax+by+c =0 ,we get

a=4

b=-3

c=2

d=
`(4*3+(-3*-2)+2)/(√(4²+(-3)²))`

=4 units
