-4, -1, 1, 3, 3.9, 3.999,
Just multiply 42 by 10 and that gives you 420 , so the real car has a length of 420cm or 4.2 metres :)
Perpendicular has slope that multiplies to -1
y=mx+b
m=slope
y=-1x+11
-1 times what=-1?
what=1
y=x+b
find b
given
(-2,3)
(x,y)
inpus -2 for x and 3 for y
solve for b
3=1(-2)+b
3=-2+b
add 2 to both sides
5=b
y=x+5 is equation
