Answer:
Step-by-step explanation:
Center (0,0)
radius = √16 = 4
Answer:
y = 1/4x + 1
Step-by-step explanation:
y = 1/4 x + b
take the point and plug it into the formula to solve for b
2 = 1/4 (4) + b
2 = 1 + b
b = 1
Answer:
A, D , and E
Step-by-step explanation:
We have that:


is the image of CD after a dilation of scale factor n.
We use the relation between the image length and object length:

Option A
If n=3/2, then

This is true.
Option B
If n=4, then

This is false.
Option C
If n=8, then

This too is false.
Option D
If n=2, then

This is true
Option E
If n=3/4, then


This is also true.
Answer:
12
Step-by-step explanation:
Answer:
x + 3y = -12
Step-by-step explanation:
y = mx + b
m is the slope = rise / run:
rise = 1
run = 3
the line is downhill so its negative
m = - 1 / 3
b is the y intercept which is when the line cross over the y axis: - 4
y = - 1/3x - 4
multiply both sides by 3
3y = -1x - 12
add x to both sides
x + 3y = -12
