Step-by-step explanation:
Open up equations and do FOIL method.
First equation:
(x + 2y)(x + 2y)
x^2 + 2xy + 2xy + 4y^2

Second equation:
(y + 2x)(y + 2x)
y^2 +2xy + 2xy + 4x^2

Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
We have

Substitute:

Convert to the slope-intercept form

<em>use the distributive property</em>
<em>add 3 to both sides</em>

Convert to the standard form

<em>multiply both sides by 3</em>
<em>add x to both sides</em>
