Given the line 4x−2y=8, find the slope.

The slope is 2.

Step-by-step explanation:

First  rewrite the equation in slope intercept form to find the slope.

4x -2y = 8

-4x          -4x

-2y = 8  - 4x    Divide both both sides by -2 to solve for y

y = -4 + 2x   rewrite it in slope intercept form.

y= 2x -4   the slope as you can see now is 2.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
