Points on the same line have the same slope.
The complete proof is:
- [tex]\mathbf{Slope\ from\ P\ to\ Q\ = \frac{F}{E}}[/tex] ------ Definition of a Slope
- [tex]\mathbf{Slope\ from\ Q\ to\ R\ = \frac{F'}{E'}}[/tex] ------ Definition of a Slope
- [tex]\mathbf{\frac{F'}{E'}= \frac{F}{E}}[/tex] ---------------- Triangle 1 is similar to triangle 2
The first blank implies that, we give the definition of slope, based on the given parameters.
This means that, we complete the blank with the formula of slope.
So, the first blank will be completed with:
[tex]\mathbf{Slope\ from\ P\ to\ Q\ = \frac{F}{E}}[/tex]
The statement on line 2 represents the definition of slope.
So, the blank will be completed with: definition of slope,
If both triangles are similar, then they have the same slope.
Hence, the third blank is: [tex]\mathbf{\frac{F'}{E'}= \frac{F}{E}}[/tex]
