Answer:
-0.2
Step-by-step explanation:
Slope (m) =ΔY/ΔX= 8-(-2)/-3-(-1)
= -1/5
= -0.2
Answer:
the distance of the 3rd car from the 7th car is
217 inch
–4(6x + 3) = -12<span>(x + 10)
</span><span> -24x - 12 = -12x - 120

Answer:
a) k = 5; (-10, -35)
Step-by-step explanation:
Given:
Co-ordinates:
Pre-Image = (-12,3)
After dilation
Image = (-60,15)
The dilation about the origin can be given as :
Pre-Image
where
represents the scalar factor.
We can find value of
for the given co-ordinates by finding the ratio of
or
co-ordinates of the image and pre-image.

For the given co-ordinates.
Pre-Image = (-12,3)
Image = (-60,15)
The value of 
or 
As we get
for both ratios i.e of
and
co-ordinates, so we can say the image has been dilated by a factor of 5 about the origin.
To find the image of (-2,-7), after same dilation, we will multiply the co-ordinates with the scalar factor.
Pre-Image
Image
Pre-Image
Image
