The city designers drawing the road map for new housing development hurricane Ln runs through the coordinates (11, 5) and (-1, 1
) on the map. Trammel-Fresno Rd. is going to run perpendicular to Hurricane Ln. What is the slope of Trammel-Fresno?
1 answer:
Answer:
-3
Step-by-step explanation:
Use slope formula to find the slope of the first road:
(y2 - y1) / (x2 - x1)
(1 - 5) / (-1 - 11)
-4 / -12
1 / 3
The slope of a line perpendicular to this line would just be the negative reciprocal of the slope:
-3 / 1 or just -3

The equations will have the same solution if one is a multiple of the other.
Equations with the same solution are
.. B . . . multiplied by -1
.. C . . . multiplied by 5
.. E . . . multiplied by 2
.. F . . . multiplied by 1/2
Count the number of times x is used as a factor of this polynomial. I count 4. Thus, this expression will have 4 zeros.
