<span>x + 3y= -11 (1)
</span><span>-9y = 33 + 3x ---->3x + 9y = -33 (2)
divide (2) equation by 2
</span>3x + 9y = -33
x + 3y = -11 (2')
and equation (1) is also x + 3y= -11 (1)
so
x + 3y= -11 (1)
x + 3y= -11 (2')

To find the equation take the slope 2/3
y-y(1)=m(x-x(1)
y-4=2/3(x-8) = 2/3x-16/3
Next solve for y
y=2/3x-16/3 +4(turn 4 into a fraction with a common denominator)
y=2/3x-16/3 + 12/3
y=2/3x-4/3
Answer:
y = 7
Step-by-step explanation:
The similarity statement
tells you which vertex from the first polygon corresponds to which vertex from the second polygon.
A is paired with W, B is paired with X, C is paired with Y, D is paired with Z.
The expression <em>y</em> + 2 is placed along side WZ which corresponds to side AD in the first polygon.
Now locate two sides, one from each polygon, that are labeled with just <u>numbers</u>. That way, you'll be able to tell what the proportion is between the two shapes.
AB and WX correspond and are labeled 5 and 3, respectively.
Now you can write a proportion:

Use the Means-Extremes Property ("cross multiply").

Answer:

Step-by-step explanation:
First find the slope:

Use the point-slope form of linear equation: 
(where m is the slope and (x₁, y₁) is a point on the line)
with the found slope and one of the points:
