Pls help due tomorrow!!!
Slope = -7; (4, -30)

y = -7x - 2

Step-by-step explanation:

To write this into an equation, we need to use the y = mx + b formula.

y = mx + b

-30 = -7(4) + b  <--- Substitute 4 as x, and -30 as y.

-30 = -28 + b  

+ 28    +28  <--- Add 28 on both sides of the equation.

-2 = b

Final equation:

y = -7x - 2

Answer:

Step-by-step explanation:

using the formula: y - y1 = m ( x - x1 )

                            : y - -30 = -7 ( x - 4 )

                            : y + 30 = -7x + 28

                            : y = -7x + 28 - 30

                             : y = -7x - 2

i think that you should ask google for the answer to that problem because if we don't know it google does

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.
