A, B, C, and D have the coordinates (-8,1), (-2,4), (-3, -1), and (-6,5) respectively. which sentence about the points is true?
Trava [24]
Answer:
Option B is correct.
Step-by-step explanation:
To check if the lines are parallel or perpendicular, we need to find the slope of lines AB and CD
A=(-8,1), B= (-2,4), C= (-3, -1), and D= (-6,5)
Slope of AB = y₂-y₁/x₂-x₁
Slope of AB = 4-1/-2-(-8)
Slope of AB = 3/-2+8
Slope of AB = 3/6
Slope of AB = 1/2
Slope of CD = y₂-y₁/x₂-x₁
Slope of CD = 5+1/-6-(-3)
Slope of CD = 6/-6+3
Slope of CD = 6/-3
Slope of CD = -2
Lines are parallel if Slope of AB = Slope of CD
Lines are perpendicular if Slope of Ab = -1/Slope of CD
So, Slope of AB = 1/2
Slope of CD = -2
So, LINE AB AND LINE CD ARE PERPENDICULAR
Option B is correct.
Step-by-step explanation:
we have that
f(x)=3x-2
g(x)=4x-1
3x-2=4x-1-------------> 4x-3x=-2+1--- > x=-1
find the value of f(x) or g(x) for x=-1
f(x)=3x-2 -------> f(-1)=3*(-1)-2 ------>
f(-1)=-5
the solution is the point (-1,-5)
using a graph tool
see the attached figure
the answer is

case (A)
The solution of the equation is the x-coordinate of the ordered pair where the
graphs of the two functions intersect.</span>
