Find the missing value so that the two points have a slope 1/2
(7, 2 )and (3,y)

The missing y -coordinate is 0.

Step-by-step explanation:

Here we know the slope but must find the y-coefficient of one of the points.

                                                         y - 2

The slope is m = 1/2 = rise / run =

                                                         3 - 7

                y - 2

or   1/2 =           which simplifies to   -2 = y - 2, which yields y = 0.

                   -4

The missing y -coordinate is 0.

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.

the first option i believe
