Answer:
y = - 4x + 20 ... slope=-4 y intercept:20
Step-by-step explanation:
2y+8x=20
2y=-8x+20
y = - 4x + 20 ... slope=-4 y intercept:20
(y = mx + b)

Answer:
15 and 27
Step-by-step explanation:
let the smaller number be n then the larger number is n + 12 and
n + n + 12 = 42, that is
2n + 12 = 42 ( subtract 12 from both sides )
2n = 30 ( divide both sides by 2 )
n = 15
and n + 12 = 15 + 12 = 27
The 2 numbers are 15 and 27
