What is the slope of a line perpendicular to the line whose equation is
12x – 3y = 81. Fully reduce your answer.
Answers
Answer:
slope of perpendicular line is -1/4
Step-by-step explanation:
slope of standard equation of line that is ax+ by = c is
slope m = -a/b
given equation is
12x – 3y = 81
comparing it with ax+ by = c
a = 12
b = -3
thus
slope of given line = -12/-3 = 4
we also know product of slope of two perpendicular line is -1
let the slope of other line be m
thus,
product of given line line and perpendicular line is -1
4*m = -1
m = -1/4
Thus,
slope of perpendicular line is -1/4

same rate, what distance can you travel in 6 hours?
Answers
Answer:
30miles
Step-by-step explanation:
You go 5 miles everyone 1 hour (you can find this out by dividing 20 by 4)
5 multiplied by 6 equals 30
20÷4=55×6=304(m+3)=36 what’s the value of m

what is the slope of (-3,2) (-5,-2)
what is the slope of (7,1) (1,-7)
Answers
Answer:
The slope of the points (-3,2) (-5,-2) is 2
The slope of the points (7,1) (1,-7) is 4/3
Step-by-step explanation:
Use rise over run (y2 - y1) / (x2 - x1)
Plug in the points given and find the slopes:
(y2 - y1) / (x2 - x1)
(-2 - 2) / (-5 + 3)
-4/-2
= 2
Find the next slope:
(y2 - y1) / (x2 - x1)
(-7 - 1) / (1 - 7)
-8/-6
= 4/3
The slope of the points (-3,2) (-5,-2) is 2
The slope of the points (7,1) (1,-7) is 4/3
