Our line equation is

where the slope m=1/2 and the y-intercept b is b=7.
Parallel lines has the same slope. Hence, their slope is always

in this case.
Answer:
he can make 5 pillow cases before runninng out of fabric
Step-by-step explanation:
+x on each side. Then -2 on each side. Then divide both sides by 6 and you have your answer
We know that
Rigid transformation:
A rigid transformation (also called an isometry) is a transformation of the plane that preserves length.
Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations"
so, it's length must be preserved
now, we will check each option
option-A:
we have (x,3y)
y-value changes but x-value will remain same
It changes length
so, this is not rigid transformation
option-B:
we have (3x,y)
x-value changes but y-value will remain same
It changes length
so, this is not rigid transformation
option-C:
(2x, y+2)
It changes length of x-value
but it is only shifting y-value
so, it changes length
so, this is not rigid transformation
option-D:
Both shifts values
but it's length will always be same
so, this is rigid transformation..............Answer
