A line segment is formed by connecting two points located at (-4,2) and (2,-1). What is the slope of this line segment? A.-3/8 B
Scorpion4ik [409]
The formula for slope is 
m= (y₂-y₁)/(x₂-x₁)
you can plug in the points that you are given to find the slope
m= (-1-2)/(2-(-4)
m= -3/6

the slope is -3/6 which reduced to -1/2

so the answer would be 
c) -1/2

Farmer brown had ducks and horses one day he noticed that all of the Animals had a total of 12 heads and 32 feet how many animal
brilliants [131]

Answer:

4 horses and 8 ducks.

Step-by-step explanation:

Let the number of ducks be d and the number of horses be h.

d + h = 12

Now ducks have 2 feet and horses have 4 so:

2d + 4h = 32

Multiply the first equation by 2

2d + 2h = 24

Subtract this equation from the second equation:

4h - 2h = 32 - 24

2h = 8

h = 4.

So there were 4 horses and 12 - 4 = 8 ducks.

vitfil [10]

Step-by-step explanation:

step 1. graph f(x) = 2x + 6

step 2. y = mx + b. (slope intercept form)

step 3. b = 6 which is the y intercept so put a dot on (0, 6) or on the y axis at 6

step 4. m = 2 so put another dot up 2 and over to the right 1 from the y intercept

step 5. draw a line through your 2 points and you are done.
