Remember that

is

. We know form our problem that

and

, so:



Now, to find

, we just need to evaluate

at 3. In other words, we are going to replace

with 3:


We can conclude that the correct answer is <span>
C.6(3) – 4 + 3^2 </span>
x = 1 and y = -11 is the correct answer.
Hope this helps.
Answer:
y = -x + 8
Step-by-step explanation:
First, plug in the slope.
y = mx + b
y = -1x + b
y = -x + b
Then, plug in the point.
7 = -(1) + b
7 = -1 + b
8 = b
The coordinates of the center is at (1, 0) and the length of the radius is 4 units.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
The standard form of a circle is:
(x - h)² + (y - k)² = r²
Where (h, k) is the center of the circle and r is the radius.
The coordinates of the center is at (1, 0) and the length of the radius is 4 units.

Answer:
y=-4x-5
Step-by-step explanation:
Use the equation of the line formula, y=mx+b
since we know that the slope is -4, we just have to find b
plug the points into the equation, y=-4x+b
(3)=-4(-2)+b
simplify
3=8+b
subtract 8 from both sides
b=-5
plug b into the equation
y=-4x-5
