Answer:
I'll set up the problem and you can do the calculation
Step-by-step explanation:
we need to complete the squares to get the equation in the general form:

where h = the x coordinate of the center
k = the y coordinate of the center
r = the radius
so looking at

we can see that if use -1 as the constant we have

doing the same for y

we can use -2 as the constant (basically you that the s
quare of the y coefficient )

so now we have to add or subtract the constant on the RHS to see what the square of the radius is according to the general form of the equation at the top
20 +1+4=25
Take the square root and you have the radius
Answer:The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run. The slope of a line is usually represented by the letter m. (x1, y1) represents the first point whereas (x2, y2) represents the second point.
