# What is the slope of the line passing through the following points:  (5,-3) , (7,3)?

Dec 28, 2015

The slope is $3$

#### Explanation:

We can easily prove it by seen that when $x$ changes its value from $5$ to $7$, $y$ changes it from $- 3$ to $3$.

So, when $x$ rises $2$, $y$ rises 6.

So, when $x$ rises by $1$, $y$ rises by $3$,

(y-rise[6]) / (x-rise[2]

simplified as

$\frac{y - r i s e \left[3\right]}{x - r i s e \left[1\right]}$
