Answer:

\sqrt{145}units

Step-by-step explanation:

Distance between 2 points

= \sqrt{(x1 - x2)^{2}  + (y1 - y2)^{2} }

Thus distance between (-2, -1) and (6, 8)

= \sqrt{ {(6  + 2)}^{2}  + (8 + 1)^{2} }  \\  =  \sqrt{8^{2}  + 9^{2} }  \\  =  \sqrt{145}  \: units

in a

given

slope(m)=1

point=(2,-4)=(x1,y1)

we know

equation of straight line

y-y1=m(x-x1)

y+4=1(x-2)

y+4=x-2

therefore x-y-6=0 is the required equation

substituting with ax+by+c=0 we get

a=1

b= -1

c= -6
