Answer:
x = 8 - y
Step by step explaination:
==>x + y = 8
==> x = 8 - y
==> substract the value
==> Done
Answer:
A
Step-by-step explanation:
Answer:
The correct choice is

Step-by-step explanation:
The given equation is

We rewrite the left hand side of the equation as a power(a number to a given exponent.

Recall that;

We apply this property to obtain;

Since the exponents are the same, the bases are also the same.
Therefore 
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
You need to find "m" and "b".
If you look at the graph, when x = 0, y is 1, so the y-intercept is 1.
y = mx + 1
To find "m", you can use the slope formula and find two points on the graph and plug it in, or you can use this:

Rise is the number of units you go up(+) or down(-)
Run is the number of units you go to the right.
If you look at the graph, from each point you go up 1 unit, and to the right 1 unit. So your slope is
or 1
y = 1x + 1
y = x + 1
