Answer:
Perpendicular: -2/5
Parallel: 5/2
Step-by-step explanation:
The slope-intercept formula is y=mx+b, where mx is the slope.
So in the equation y = 5/2x, 5/2 is understood as the slope.
To find a perpendicular slope you have to do the opposite (sign), reciprocal (flip denominator and numerator) of the original number.
Therefore 5/2 become negative, and then the numerator and denominator switch sides. (-2/5)
Parallel slope is the exact same as the original one so nothing changes. (5/2)
Answer:
C. Town A has the greater average number of dogs per neighborhood.
Step-by-step explanation:
First, find Town A's average number of dogs per neighborhood. Since the graph is a straight line, you can find the number of dogs per neighborhood by dividing a given y-value by its x-value counterpart:
(4,60)
60 dogs / 4 neighborhoods
<u>15 dogs / neighborhood.</u>
Now, we must find the average number of dogs per neighborhood in Town B. Since the equation is y = 10x, where x is the number of neighborhoods, in 1 neighborhood, there are 10 dogs:
<u>10 dogs / neighborhood.</u>
Finally, compare the two values:
15 > 10
<u>C. Town A has the greater average number of dogs per neighborhood.</u>
