Answer:

y = 1/2x +7

Step-by-step explanation:

I like to start with the 2-point equation for a line.

y = (y2 -y1)/(x2 -x1)(x -x1) + y1

y = (9 -8)/(4 -2)(x -2) +8 . . . . . fill in point values

y = 1/2(x -2) +8 . . . . . simplify a bit

y = 1/2x +7

zloy xaker [14]

Answer:

27 years old

Step-by-step explanation:

Let Alvin's age be x and Elga's age is y:

y - x = 15

x + y = 27

2y = 42 (use elimination method)

y = 21

x = 6 (plug it back into either equation)

Therefore Alvin is 6 and Elga is 27
