Answer:
c
Step-by-step explanation:
for the most recent your daddy
X - y = -5
-y = -x - 5
y = x + 5...slope here is 1. A perpendicular line will have a negative reciprocal slope. All that means is flip ur slope and change the sign. So our perpendicular line will have a slope of -1.
y = mx + b
slope(m) = -1
(4,7)...x = 4 and y = 7
now we sub and find b, the y int
7 = -1(4) + b
7 = -4 + b
7 + 4 = b
11 = b
so ur perpendicular equation is : y = -x + 11 <==
The answer is 6 5/6.
Do you understand why?
If not...be sure to leave comment telling me what u r having problem with.
Glad to help!
