Step-by-step explanation:
The list of <em>second numbers</em> of the ordered pairs is the <em>range</em>.
___
The second number of the first pair is 4; the second number of the second pair is 3. The only 4-number answer choice containing these two numbers is (d). You don't even have to work the whole problem to make the proper choice.
From left to right, the line slants upwards like in this image:
If 
, then we can immediately cancel the factors of 
:
Factorize the numerator and denominator:
Next, if 
, then
Answer:
-1/6
Step-by-step explanation:
To find the slope we use
m = (y2-y1)/(x2-x1)
= (-4-8)/( 1-3)
= -12/-2
=6
We want a line perpendicular, so we need the negative reciprocal
- (1/6)
-1/6
