Answer:
y = -1/2 x + 2
Step-by-step explanation:
Which of the following equations describes the line shown below? Check all
that apply.
(-4, 4)
(2, 1)
The standard equation of a line is y = mx,+b
m is the slope
b is he y-inttercept
Get the slope
Slope m = y2-y1/x2-x1
Substitute the coordinate
M = 1-4/2-(-4)
M = -3/6
M = -1/2
Substitute m= -1/2 and (2,1) into y = mx+b
1 = -1/2(2)+b
1 = -1+b
b = 1+1
b=2
Get the equation
Recall y =mx+b
y = -1/2 x + 2
It actually says additional hours, but because it is not a choice here, it is 28 hours!
Answer: 6 teams
Step by step:
3 people=1 group
3+3=6
6 people taken out of 18
2 groups already
3+6=9
9 out of 18 people taken
3 groups made
9+3=12
12 out of 18 people taken
4 groups made
12+3=15
15 out of 18 people taken
5 groups made
15+3=18
18 out of 18 people taken
Answer: 6 groups made
Short step by step:
18 divided by 3 equals 6
Or
3 times 6 equals 18
I really hope that made sense
Answer:
x=-3, y=9. (-3, 9).
Step-by-step explanation:
-9x-5y=-18
4x+5y=33
---------------
-5x=15
x=15/-5
x=-3
4(-3)+5y=33
-12+5y=33
5y=33-(-12)
5y=33+12
5y=45
y=45/5
y=9
