Answer:
y + 1 = 3(x - 1)
Step-by-step explanation:
The given point is (1,-1) meaning that x1 = 1 and y1 = -1
The slope of this line is m = 3 because we go up 3 and over to the right 1 (eg: go from the point (1,-1) to (2,2) to see this in action)
Plug these three pieces of info into the point slope formula below
y - y1 = m(x - x1)
y - (-1) = 3(x - 1)
y + 1 = 3(x - 1)
3, -1
Step-by-step explanation:
It goes 3 to the positive side
and one down side
Answer:
7020
Step-by-step explanation:
The letter could be any 1 of the 26 and it could be placed in any 1 of 3 places so this makes 26*3 = 78 possibilities.
For each of these there is any one of permutations of 2 digits from 10
= 10P2 = 10! / 8! = 10*9 = 90.
So the answer is 78 * 90 = 7020.
Note I am assuming that the 2 digits picked are different - no duplicates.

Answer:
y = x + 2
y = 2x
y = x + 5
y = 0.5x
Step-by-step explanation:
For the first three, I don't know how to explain this to you. This is very simple math, I am certain that you would have been able to do this in two minutes if you applied yourself. It would be much faster if you did the work yourself and only used brainly for things that you truly don't understand.
For the fourth answer, consider:
x is miles per 60 minutes.
y is miles per 30 minutes.
30 is half of 60, or 0.5 times 60.
Therefore, y will be equal to 0.5 times x.
y = 0.5x.
