Find the distance between I and J.
are they vectors?
I tryed to draw it what I had was a line straight down & then cross it in the middle then theres J(3,2) with a black dot under the 3 & a x to the right of the middle line then on the left under the line this is there /(-5,-4)
& a black dot above the 5
I don't know if they are vectors or not
Need help
could you upload an image of it or something?
u have given the cordinates of J cam u give the same for I
i think ans is 10 units
ithink the question is to find the distance between I(-5,-4) and J(3,2)
|dw:1356161987814:dw|
u can use simply the distance formula to find the distance between (x1,y1)& (x2,y2) which is d= sqrt((x2-x1)^2 +(y2-y1)^2)
Theres a black dot below the 3 & a black dot above the 5
if you have the two coordinates, all you have to do is find the difference in both the x-axis and y-axis and then square both numbers, add them together and compute the square root.
thus reqd distance is sqrt((-5-3)^2 +(-4-2)^2) =sqrt(64+36)=sqrt(100)=10
