The point-slope form:

We have the point (1, 6) and the slope m = 7/3. Substitute:
<em>use distributive property</em>
<em>add 6 to both sides</em>
<em>multiply both sides by 3</em>
<em>subtract 7x from both sides</em>
<em>change the signs</em>

Answer:
point-slope form: 
slope-intercept form: 
standard form: 
Distribute the 2 to get the pink box
10x + 2y = 18
Then if we are subtracting the bottom equation from the pink box
10x + 2y = 18
-(10x -7y = -18)
9y = 36
y = 4
Every two triangles are similar. Therefore the sides of triangles are in proportion.
We have the equations:
1.
<em>cross multiply</em>
<em>divide both sides by 5</em>

<em>subtract 3 from both sides</em>

--------------------------------------
2.
<em>cross multiply</em>

<em>divide both sides by 3</em>

------------------------------------------
3.

<em>cross multiply</em>
<em>divide both sides by 5</em>

<em>subtract 12 from both sides</em>

----------------------------------------------
4.
<em>cross multiply</em>

<em>divide both sides by 3</em>
