Lines B and C are perpendicular ⇒ answer C
Step-by-step explanation:
The product of the slopes of the perpendicular line is -1
The slopes of the parallel lines are equal
The slopes of two lines are and
1. If × = -1, then the two lines are perpendicular
2. If = , the the two lines are parallel
The equation of a line in slope-intercept form is y = m x + c, where m is
the slope of the line
Line A: y = x + 2
The slope of the line is =
Line B: y = x + 7
The slope of the line is =
Line C: y = 2 x + 4
The slope of the line is = 2
Line D: x +
The slope of the line is =
∵ =
∵ = 2
∵ × 2 = -1
∴ Line B and Line C are perpendicular because the product of their
slopes is -1
Lines B and C are perpendicular
