<h2>
Answer:</h2>
We will use substitution to solve this system for x.
Now that we know what x is, we can determine y by pluging in -3 for x in one of the original equations. I will use the first one.
We now have our solution.
D. 
We can check our answer by pluging the solution into one of the original equations to see if both sides equal each other. I will use the first equation.
Since the equation checks out, our solution is correct.
Answer:
5 is the leading coefficient
Answer:
If the interior angle of a regular polygon is 160 degrees, then the exterior angle is 20 degrees. The sum of all exterior angles is 360 degrees so there must be 360/20 sides = 18 sides.
An 18 sided polygon is known as an octadecagon.
The dlope-intercept form:
m - slope
b - y-intercept (0, b)
The formula of a slope:
We have two points from the graph
x-intercept: (-1, 0)
y-intercept: (0, - 1) → b = -1
Substitute to the formula of a slope:
<h3>Answer: y = -1x - 1 = -x - 1</h3>
