(3,2),(-9,6)
slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3

y = mx + b
slope(m) = -1/3
use either of ur points...(3,2)....x = 3 and y = 2
now we sub into the formula and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur equation is : y = -1/3x + 3 <==

One number is 4 more than another. the difference between their squares is 64. what are the numbers
lora16 [44]
We have to set up 2 different equations if we are to solve for 2 unknowns.  The first equation is x = y + 4.  One number (x) is (=) 4 more than another (y + 4).  Since we have determined that x is larger (cuz it's 4 more than y), when we set up their difference, we are going to subtract y from x cuz x is bigger.  The second equation then is x^{2} - y^{2} =64.  In our first equation we said that x = y + 4, so let's sub that value in for x in the second equation: (y+4) ^{2} - y^{2} =64.  Expand that binomial to get y^{2} +8y+16- y^{2} =64.  Of course the y squared terms cancel each other out leaving us with 8y + 16 = 64.  Solving for y we get that y = 6.  Subbing 6 in for y in our first equation, x = 6 + 4 tells us that x = 10. Yay!

umka2103 [35]
If you switch it around, it'll be: 1,707 - 264

Subtract:

1,707 - 264 = 1443

Answer = 1,443

HeLP me ASAP PLEASE ASAP i will give 50 points for the right answer
maksim [4K]
I think the first answer is 41/100

Explanation:
I worked out how likely you would be to get a green marble based off of the answers, then added them together and divided by 3

2/5 = 40/100
9/16 = 50/100
3/9 = 33/100

40+50+33 =123
123/3 =41

Then for the second answer I think it’s 50% (1/2)
