Answer:
2
Step-by-step explanation:
To find the slope of a line given two points [tex](x_1,y_1) \text{ and } (x_2,y_2)[/tex] you could use the formula: [tex]\frac{y_2-y_1}{x_2-x_1} \text{ or even } \frac{y_1-y_2}{x_1-x_2}[/tex].
However, what I'm fixing to do is equivalent to that except I think easier to remember.
You line up the points vertically and subtract, then put 2nd difference over 1st difference.
Like this:
( 3 , 4)
- ( 5 , 8)
---------------
-2 -4
So the slope is -4/-2=4/2=2.
The slope is 2.
