4x + 2x = < y
This is because the opposite sides (which is 4x and 2x) of a triangle add up to the exterior angle (<y).
We have to find X.
As you know:
because the angles of a triangle add up to 180.
When we add them:
The 9 is multiplying with the X. We want X only and not 9 with it. So, when we take 9 to the other side, it becomes divide. As a result, the answer to x is:-
Substitute value of x into 4x and 2x to find the exterior angle:-
4x:
2x:
When we add them we get the answer for angle Y:-
Therefore, we can conclude that:
The domain is all of the possible x values.
The range is all of the possible y values.
When writing the coordinates for a point, we know it should be in this format: (x,y).
Thus we get:
Domain = {-9,4,5}
Range: = {2, 4, 17}
(TIP: do not repeat any values. Only write each number once.)
(TIP: Order the values from least to greatest.)
I I believe it’s infinite because they are the same line.
If you multiply the bottom equation by 9, you get the top one.

Answer:
y - 10 = -1/2(x + 4)
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>m</em> = -1/2
Point (-4, 10) → x₁ = -4, y₁ = 10
<em />
<u>Step 2: Find</u>
- Substitute in variables [Point-Slope Form]: y - 10 = -1/2(x - -4)
- Simplify: y - 10 = -1/2(x + 4)
