Answer:
x+y+5=0
Step-by-step explanation:
the intersection of x-2y=0 and 3x+y+5 is (;)
=> the line : x+y+5=0
The distance formula is:
D = sqrt((x2-x1)^2 + (y2-y1)^2)
D= sqrt ((6-2)^2 + (8-1)^2)
D = sqrt(4^2 + 7^2)
D = sqrt( 16 + 49)
D = sqrt(65)
D = 8.06
Rounded to the beat tenth = 8.1 units.
The answer is C. 8.1 units
A is the answer!! Hope it helps
