Through (2, 2), y-intercept 10 a. y = x + 10 c. y = -4x + 10 b. y = 4x + 10 d. y = x - 40

C. y = -4x +10

Step-by-step explanation:

Equation of a line is found by the formula y = mx +b

Where m is the slope and b is the y intercept

we see that y-intercept is given as 10, so b = 10 and we plug in the coordinate (2,2) into the equation to find the slope (m). We plug in x = 2 and y = 2. Shown below:

We know the value of m to be -4 and b to be 10, thus we can write the equation as:

Answer choice C is right.

c. y = -4x + 10

Step-by-step explanation:

y = mx + b where b = y -intercept = 10

so

y = mx + 10

Plug in (2,2) to find slope m

2 = 2m + 10

2m = -8

m = -4

Slope m = -4

Equation

y = -4x + 10

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

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.
