Answer:

P' = (3, -5)

Step-by-step explanation:

Rotation 180° about the origin is the same as reflection across the origin. The transformation is given by ...

(x, y) ⇒ (-x, -y) . . . . . . the signs of the coordinates are both changed

P(-3, 5) ⇒ P'(3, -5)

In the equation (x+2)2+(y-3)2=4, the diameter of the circle is... 16 4 3 2

julia-pushkina [17]

Answer:

Step-by-step explanation:

The given equation of circle is:

$(x+2)^2 +(y-3)^2 =4$

$(x+2)^2 +(y-3)^2 =2^2$

Equating it with:

$(x-h)^2 +(y-k)^2 =r^2$

We find:

$r^2=2^2$

$\therefore r=2$

Radius of the circle = 2 units

Therefore,

Diameter of the circle = 2*2= 4 units

How do I plot y=2x-4

Anvisha [2.4K]

The formula: y = mx + b
m = slope or rise/run
b = y-intercept

So, the y-intercept would be -4 and the slope would be 2.

First, you would need to find the y-intercept, -4.

Next, you would use the slope, 2, to find the coordinate. Remember, 2 = 2/1
You would rise 2 and run 1.

The coordinates to form a line would be (1,-2), (3,2), and (-1,-6). All you would need to do is draw a line through the coordinates.

I hope this helps!
