Answer:
Let a and b integers and suppose that are even numbers. Then, exist integers k and m such that
and
.
Then,

Since, k and m are integers then n=k+m is an integer. Then, since a + b is of the form 2 by an integer n, then a + b is an even number.
Answer:
y = -x-2
Step-by-step explanation:
We are given a slope of -1 and the y intercept of -2
The slope intercept form of the equation for a line is
y = mx+b
where m is the slope and b is the y intercept
y = -1x +-2
y = -x-2
Answer:
y = x + 7
Step-by-step explanation:
3y - 3x = 21
3y/3 - 3x/3 = 21/3
y = x + 7
