Answer:

Step-by-step explanation:
Use the circle equation, 
Plug in the center and radius:

Simplify:

So, the equation is 
Answer: y= -3/2x + 2
y= -3/2 + b
5 = -3/2 * -2 + b
5 = 3 + b
2 = b
Slope: 3/2.
Y intercept: -3
Equation: Y=3/2x-3
Answer:
Step-by-step explanation:
Figure A maps to figure B with a scale factor of 4/9, hence the value of x is x = 54
<h3>What is a
transformation?</h3>
Transformation is the movement of a point from its initial point to a new location. Types of transformation are<em> reflection, rotation, translation and dilation.</em>
Dilation is the increase or decrease in the size of a figure.
Figure A maps to figure B with a scale factor of 4/9, hence:
4/9 * x = 16
x = 54
Figure A maps to figure B with a scale factor of 4/9, hence the value of x is x = 54
