Answer:
2x + y = 4
Step-by-step explanation:
2x + y = 9 => y = -2x + 9
Parallel lines have the same slope so m = -2
Given (-1,6)
y = mx + b
6 = -2(-1) + b
6 = 2 + b
b = 4
so y = -2x + 4 or 2x + y = 4
5 x 0.4 = 2 and

= 1.4142....... which is an irrational number
#1 is a pentagon.
It's regular, because all the sides are the same length.
#2 is a hexagon.
It's not regular, because the sides don't all have the same length.
