Answer:

The correct answer is b) x - y + 1 = 0

Step-by-step explanation:

In order to find this, start by finding the slope using the two points given.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - 2)/(4 - 1)

m = 3/3

m = 1

Now that we have the slope, we can plug into point slope form along with either point. Then we can solve for 0 to see which equation is correct.

y - y1 = m(x - x1)

y - 2 = 1(x - 1)

y - 2 = x - 1

-x + y - 2 = -1

-x + y - 1 = 0

x - y + 1 = 0

Find the equation of the circle whose center and radius are given.

vredina [299]

As i said before put the center instead of (h,k) in the general formula and put r=1
so (x-(-2))^2 + (y-(-5)^2 = 1
(x+2)^2 + (y+5)^2 = 1

Please help and explain. The question is in the picture below.

Murrr4er [49]

Answer:

D and yes

Step-by-step explanation:

$\frac{x}{4}$ + 1 = -3 If we multiply both sides of the equation by 4 will will get the second equation

(4) $\frac{x}{4}$ + (4) 1 = (4) -3

x + 4 = -12 We solve this for x by subtracting 4 from both sides.

x = -16

Plug -7 into both equations and you will see that it is a solution

$\frac{x}{4}$ + 1 = -3

$\frac{-16}{4}$ + 1 = -3

-4 + 1 = -3

-3 = -3

x + 4 = =12

-16 + 4 = -12

-12 - -12
