Answer:
3x - y =13
Step-by-step explanation:
- y - y1 = m(x - x1)
- y - 2 = m(x - 5)
- distribute
- y - 2 = 3x - 15
- jump -2 across the equal sign and change the sign
- y = 3x - 15 + 2
- combine like terms
- y = 3x - 13
- use this equation to find the standard form
- y = 3x - 13
- jump the x and change the sign
- -3x + y = -13
- x must be positive, so change the sign of everything
- 3x - y = 13
Answer:
y=-3x+4
Step-by-step explanation:
3x+y=4
y=4-3x
y=-3x+4

Andy maximal age= 13.3
Matt maximal age= 21.7
I will translate the problem into 2 equation where X is Andy's age and Y is Matt's age.
Y+5= 2X
Y= 2X-5
X+Y<35
From this equation, it is clear that you won't be able to find their age. But you can find maximal age of Andy and Matt by changing X+Y<35 into X+Y=35
Inserting the first equation to the second equation you will get:
X+Y=35
X+ (2X-5)=35
3X= 35+5=40
X=13.3
X+Y=35
13.3+Y=35
Y= 21.7
I'm 100% positive that the answer is 2 I posted my work below
