Here's a graph. Remember that the y intercept crosses the y axis.
Answer:
perpendicular
Step-by-step explanation:
First we need to dtemine the slopes of the line
For line 1
L1: (-4, 6) (-3,-1)
m1 = y2-y1/x2-x1
m1= -1-6/-3+4
m1 = -7/1
m1 = -7
For line 2:
L2: (8,9) (15, 10)
m2 = 10-9/15-8
m2 = 1/8
Take their product
m1 * m2 = -7 * 1/7
m1m2 = -1
Since the product of their slopes is -1, hence they are perpendicular
Answer:
See below.
Step-by-step explanation:
A = (-2/3, 0)
B = (-1/6, 0)
C = (1/2, 0)
D = (4/3, 0)
