On a coordinate plane, point a is located at (7,4), and point b is located at (-8,4). what is the distance between the two points?

The distance formula is d=\sqrt{(x_{2}, x_{1})^{2} +(y_{2}, y_{1})^2

7=x1

4=y2

-8=x2

4=y2

Just plug in the missing values into the equation and solve the equation :)

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
