Answer: The slope of a line is m=(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the two points on the line.

So we have x1=0,y1=4 and x2=-8 y2=-1 this gives us =(-1-4)/(-8-0) =5/8

I don't know if this helped..

Answer:

A)(7,-9)

Step-by-step explanation:

we know x=7

so put it in the equation

y= -2(7)+5

y=-9

we always put the x coordinate first and then the y coordinate so the answer is (7,-9)

Number 36 please for geometry

Mumz [18]

Answer:

(x - 1)² + (y + 1/2)² = 65/4

Step-by-step explanation:

Given: the endpoints of the diameter are (3, 3) and (-1, -4). a( To determine the center of this circle, find the midpoint of the line segment connecting these two points:

3 - 1

x = -----------

and

-1

y = ----------

The center is at x = 1 and y = -1/2: (1, -1/2).

b) The radius is half the diameter. The diameter is the distance between the two endpoints given, that is, the distance between (-1, -4) and (3, 3):

diameter = √(4² + 7²) = √(16 + 49) = √65; therefore,

radius = (1/2)√65.

square of the radius = r² = 65/4

The general equation of a circle with center at (h, k) and radius r is

(x - h)² + (y - k)² = r². In this case, the equation is:

(x - 1)² + (y + 1/2)² = 65/4

Simplify – 2(7x – 3)

ANTONII [103]

All you need to do here is multiply the outside number by both 7x and -3.

When done correctly it should look like this:

-14x+6

Thats the answer.

7 times 2 gives you 14 but when multiplying mixed signs it turns negative so it would be -14.

negative 3 times negative 2 gives you 6. Both signs are negative, and you would suppose it would turn into a negative but thats only true when both signs are mixed. Both the 3 and the 2 are negative, making the signs the samez giving you positive

Dont forget to make this the brainliest answer to help those in need. also add a 5 star and a heart. thanks for the support hope it helped. have a nice day

Answer:

Step-by-step explanation:

x - 5/8 + 1/8 = 6/8 = -3/8 if u simplify

to simplify u need to see how many times it can be shrunk to do it

hope that helped
