Answer:
B(-1,-3)
Step-by-step explanation:
let the coordinates of B be (x,y)
Mid point of AB = (x₁+ x₂/2, y₁+y₂ /2)
= (-3 +x/2 , -5+y/2)
Mid point of AB is M(-2,-4)
(-3 +x/2 , -5+y/2) = (-2, -4)
-3 + x /2 = -2 ; -5+y/2 = -4
-3 + x = -2 * 2 ; -5 + y = -4 * 2
-3 + x = -4 ; -5 + y = -8
x = -4 +3 ; y = -8 +5
x = -1 ; y = -3
B(-1,-3)
Point slope form- y-4=(x+2)
Slope intercept- y=x+6
Solution
Step 1
Two distinct lines intersecting each other at 90° or at right angles are perpendicular to each other.
Hence apply this to question 8 the type of lines shown in the figure is perpendicular lines. Option C
Step 2
To explain this as stated above line A and line B intersect each other at a right angle hence line A and B are perpendicular lines. The line segments are seen below.
