Yes all the points lay in the line.
Insert the x coordinate into x giving you your y
Answer: step-by-step
Step-by-step explanation:
answer: 10
to solve you have to follow PEMDAS
Answer:
Step-by-step explanation:
(x²-6x)+(y²+8y)=-21
(x²-6x+9)+(y²+8y+16)=-21+9+16
(x-3)²+(y+4)²=4
center=(3,-4),radius=√4=2
To start we need to find out the number of total students:
7+8+5+12=32
Then we know that 8 out of the 32 students chose green:
8/32=0.25
0.25•100%=25%
Answer: Y = -2x + 10
Step-by-step explanation:
You can find the slope by using the slope formula
which is y2 - y1 over x2 - y1
4 - 2 = 2
3 - 4 = -1 so the slope is -2/1 or just -2x
Now to find b we plug in any 2 points
0 = -2(5) + b
0 = -10 + b
add 10 to both sides so -10 cancels out
10 = b
or
b = 10 (same thing)
so the equation would be
y = -2x + 10
