Answer:
Let's see the first two points: (-7, 5) and (-5, 9)
The line passes these points has a form of: y = Mx + b
=> 5 = (-7)M + b
9 = (-5)M + b
Subtract the 1st equation from 2nd equation, we have:
4 = 2M
=> M = 2
Substitute M back into 1st equation:
=> 5 = (-7)*2 + b
=> b = 19
=> y = 2x + 19
or y - 5 = 2x + 14
or y - 5 = 2(x + 7)
=> Option A is correct
Hope this helps!

Step-by-step explanation:
Let Jack's present age be x
Hence, his fathers present age=4x
Jacks age after 5 years= (x+5)
Jacks Fathers age after 5 years= (4x+5)
We know.. that the difference between their ages fives years later is 10.. hence
4x+5-(x+5)=10
4x+5-x-5=10
3x = 10
x= 3.3 years old...
Hence,
Jacks present age = 3.3 years
Fathers present age= 13.2 years...
Hope it helps .. I know that the answer comes in decimals... but the questions' like that..
Each of the four sets has a K, Q and J.
That is 3 (each card) times 4 (for each suit) = 12
Each card deck is 52 cards.
The answer is 12/52 or 3/13
Answer:
