Y=-x+b
plug in x = 4 and y = 1 to find b
1 = -4 + b and we know that if you add 5 and -4 you get 1. So ...
5 = b so if we plug that in
y= -x + 5
which is the same as y + x = 5, So it would be A
Solve by substitution


Just plug in y=-x-1 into y+x=3
So we get:

Simplify that:

And since that is not true, that means this system of equations has no solutions!
16
∧
4 X 4
∧ ∧
2 X 2 2 X 2
The answer is 2 x 2 x 2 x 2 or 2⁴ This would have worked as well had you broken
down 16 into 8 x 2. You would get the same answer as the 8 would break down into 4 x 2 and the 4 would break down into 2 x 2.
Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = -
x + 4 ← is i slope- intercept form
with slope m = - 
Parallel lines have equal slopes, thus
y = -
x + c ← is the partial equation
To find c substitute (6, 5) into the partial equation
5 = - 2 + c ⇒ c = 5 + 2 = 7
y = -
x + 7 ← equation of parallel line
