Scale factor is defined as
s=size of image / size of preimage.
Here BO is preimage.
B'O'=BO' is image, since the position of B is invariant, so B=B'.
So scale factor = B'O'/BO = 9/27 = 1/3.
D ? Cuz it’s the only one that acknowledges 6
Y=mx+b
m=slope
given
y=4x+5
m=4=slope
2.
for the points (x1,y1) and (x2,y2), the slope of the line passing trhough those points is (y2-y1)/(x2-x1)
given
(1,6) and (3,10)
slope=(10-6)/(3-1)=4/2=2
function 1 slope is 4
function 2 slope is 2
4>2
the first one has greater rate of change
We can't see any given circle. The general form for a circle centered at the origin with radius r is
